NOTES:
Structure:B-chromosome banding pattern reveals constitutive  
heterochromatin at two locations which are of particular  
interest. The large band at the end of the long arm spans the  
site of the controlling element for nondisjunction as well as the  
region in which chiasmata usually occur. The centromeric band  
spans the sensitive site at which chromatids adjacent to the  
centromeres"stick" during the nondisjunction process.

NOTES:
origin: from centric regions of As by pericentric breaks in metas  
or proximal breaks in the long arms of acros. Centric breaks will  
also produce a new small meta from two acros, or a submeta or  
even an acro. Such products consist of a centromere with one or  
two late replicating regions alongside. The new chromosomes will  
have a novel and unusual structure and are candidates for nascent  
Bs. See text for further useful discussion and fig.

TITLE:
The distribution of repetitive DNAs between regular and supernumerary chromosomes in species of Glossina (Tsetse): a two-step process in the origin of supernumeraries.

NOTES:
In Glossina austeni satellite DNA 1.682 makes up 20% of the total  
genome. Total satellite was radiolablelled and used as a probe  
for in situ hybridisation. The satellite hybridised mainly to the  
telomeres of the Bs but with a minority component to the  
centromeres of the Bs, to L1, X and Y. No appeciable heterologous  
reaction of sat 1.682 on G. mositans. Satellites of G.austeni and  
G. morsitans are unrelated in sequence. No extensive satellite  
DNA similarity between B and Y and they are not directly related  
in terms of the origin of the Bs.
Two-step process of origin of Bs rests on uniformly  
heterochromatic state of the Bs and the amplification of large  
blocks of satellite DNA at the chromosome ends. The first step  
involved the duplication and subsequent heterochromatinisation of  
an A chromosome segment (probably the Y), followed by satellite  
DNA amplification and heterochromatinisation.

KEYWORDSI:

NOTES:
In Glossina morsitans morsitans there are two satellite DNAs  
1.685 and 1.677 which together comprise 8% of the genome. Total  
satellites were radiolabelled and used as homologous probes. Sat  
1.685 hybrised mainly to telomeres and centromeres of Bs and to  
minor sites on all As and sex chromosomes.
Sat 1.677 hybridised to one end of the Bs and to a substantial  
telomeric part of one arm of each of the As, including the Y.  
Molecular analysis shows no direct relation between the Bs and  
the Y. 
No appreciable heterologous satellite reaction of 1.682 of  
G.austeni on G. morsitans morsitans. Satellites of the two  
species are unrelated sequences.
Two-step process of origin of Bs rests on uniformly  
heterochromatic state of the Bs and the amplification of large  
blocks of satellite DNA at the chromosome ends. The first step  
involved the duplication and subsequent heterochromatinisation of

NOTES:
nuclearphen:Bs no significant effect on size of As at mitosis.  
Each B increases nuclear DNA by about 5%. Bs at metaphase of  
mitosis have 1.7 times as much DNA per unit volume as As. Total  
nuclear dry mass of interphase nuclei increases with increasing  
Bs up to 4B and then decreases. Total protein and nuclear RNA  
increase up to 4B. Histone shows continuing increase with Bs. Dry  
mass,RNA,total protein and histone show odd-even effect. Dry  
mass, nuclear RNA and total protein are disproportionately high  
in evens while the reverse is true for histnes.

TITLE:
The effect of supernumerary chromosomes on meiosis in Puschkinia libanotica (Liliaceae).

NOTES:
recomb:Bs increase chiasmata of As additively and one B causes  
one extra chiasma. The increase in chiasmata is the result of an  
increased frequency in each bivalent, proportional to length.  
Regardless of number (o-4) Bs reduce the between cell variance  
(bcv) by about one third. In the absence of Bs chiasmata are  
mainly terminal, but when Bs are present chiasmata become more  
proximal and each of the extra Bs enhances this effect. The  
effect on chiasma frequency and distribution is confined to the  
long arm of the bivalents, and the short arms are unaffected.

meiosis:no relation in pairing between As and Bs. 2Bs form IIs  
(90%) and Is (10%); 3Bs form III (51.7%), I+II (40.0%) and I+I+I  
(8.3%); 4Bs form IV (55.0%), II+I (21.7%), II+II (15.0%), II+I+I  
(8.3%) and none with all univalents. Some micronuclei of unequal  
size found at interphase I, and up to 25-30% of cells may contain  
micronuclei in plants with 4 or 5 Bs. Plants with 1B showed up to  
10% laggards at AI. Nondisjunction may affect some multivalents  
at anaphase.

An additional mechanism by which B chromosomes are maintained in maize.

NOTES:
transinher:in a translocation heterozygote viable microspores  
carrying only a normal A are expected to be produced in equal  
numbers to those carrying the translocation of A-B chromosomes,  
but grains carrying the Bs in the translocation produced 56-59%  
of kernals instead of the expected 50% or less. Basis of the  
deviation not known, but constitutes an additional mechanism for  
accumulation, in addition to that of nondisjunction and  
preferential fertilisation. See paper for more detail.

TITLE:
Effects on cytokinesis and sperm formation of a B-isochromosome in Metaleptea brevicornis adspersa (Acridinae,Acrididae).

NOTES:
meiosis:arms of iso-B are completely  paired at pachytene in 100%  
of cells. At diplotene,diakinesis and M1 the B forms a ring in  
more than 90% of cells, with interstitial chiasmata. At M1 the B  
was oriented at the equator in 30% of cells, and this correlates  
with AI lagging. The lagging Bs disturb cell division and impede  
normal telophase separation with subsequent formation of  
rstitution nuclei, and simultaneously the spindle is displaced  
and an unequal cytokinesis occurs in which a large diploid cell  
and a small anucleated bud are formed. The abnormal cell division  
is also observed at second division, but less frequently. Bs thus  
lead to abnormal sperm production above that of the 0B level.

A new mechanism by which B chromosomes may be maintained in maize populations.

NOTES:
transinher: in a translocation heterozygote viable microspores  
carrying a normal A are expected to be produced in equal numbers  
to those carrying the translocated A and B chromosomes, but  
grains carrying the Bs in the translocation produced 56-59% of

deviation is unknown, but it constitutes an an additional  
accumulation mechanism over that which exists for nondisjunction  
at pgm 2 and preferential fertilisation.

The effect of B chromosomes on meiotic and pre-meiotic spindles and chromosome pairing in Triticum/Aegilops hybrids.

NOTES:
Recombination: in F1 hybrids of T.aestivum x Ae.mutica with and  
without Bs, in which all chromosomes are in a monosomic  
condition, there are four pairing classes: and the overall means  
are comparable for hybrids with and without Bs.
In various other hybrid situations, in genotypes where pairs of  
homologues co-existed with Bs, there was similarly no reduction  
in pairing due to Bs. Also, in diploid Ae.mutica with 0-4Bs there  
was no effect of the Bs on mean chiasma frequency.
A significant drop in chiasma frequency was seen in F1 hybrids of  
T.aestivum x Ae.mutica with Bs, and in T.aestivum x Ae.mutica  
nullisomic for wheat chromosomes 5D with Bs, at temperature  
regimes of 12 degrees C. No asynapsis occurred in similar hybrids  
in the absence of mutica Bs at these low temperatures. Low  
temperature sensitive phase lies early in pre-meiotic interphase.  
Ae.mutica Bs interact with specific loci in the A-complement.

NOTES:
populations:Bs sampled in six regional groups on the island of  
Oland (Sweden). Group 1 northern and central Oland where a=sandy  
soil, b=moraine,c=alvar areas; and groups 2 southern Oland where  
a=sandy soil,b=moraine and c=alvar areas. In group 1a there were  
22 pops with a mean of 21.2% Bs and a range from 0-65% (average  
Bs per plant=0.38). In group 1b there were 17 pops with a mean of  
12.1% Bs and a range from 0-35% (average Bs per plant=0.25). In  
group 1c there were 16 pops with a mean of 12.1% Bs and a range  
of 0-35.7% (average Bs per plant=0.18). In 2a 12 pops with a mean  
of 5.8% Bs and a range from 0-15% (average Bs per plant=0.09). In  
2b 4 pops with mean of 6.4% plants with Bs and a range of 0-15%  
(average Bs per plant=0.08). In 2c 25 pops with a mean of 5.7%  
plants with Bs and a range of 0-20% (average Bs per plant=0.08).
Significant variation in B frequency between groups, and a  
geographical distribution of Bs in Oland. Correlation of B  
frequencies and various soil types was studied, and only between  
B frequency and soil organic matter was there a significant  
relationship. Bs found to be more frequent in populations growing  
on soils low in organic matter; i.e. conditions most favourable  
to the species.

KEYWORDSII:

TITLE:
Cytogenetics of accessory chromosomes in Phleum phleoides.

NOTES:
Populations: five main areas of distribution sampled in Sweden.  
All belong to the most arid districts. Overall frequency plants  
with Bs = 31.1%, with average number Bs/plant=0.63. Significant  
differences between areas, but reasons for differences not known  
from this study. Ecological factors might be important on Oland.
1. Skane: 5 pops,plants with Bs 9.1-100.0%, mean=49.4, mean  
Bs/plant=1.11.
2. Vastergotland: 12 pops, plants with Bs 0.0-60.0%, mean=32.1,  
Bs/plant=0.56.
3. Oland: 18 pops, plants with Bs 0.0-35%, mean=11.4, mean  
Bs/plant=0.18.
4. Uppland: 24 pops, plants with Bs 0.0-86.7%, mean=42.6, mean  
Bs/plant=0.95.
5. Gotland: 20 pops, plants with Bs 4.5-88.2%, mean=31.1, mean  
Bs/plant=0.63.

Meiosis: Univalents usually located at pole at M1, but when near  
the equator may or may not divide A1, with little elimination.  
2Bs pair in 98% of cells and micronuclei are virtually absent.  
With 3Bs 38/47 cells had II+I, 8/47 had I+I+I and one cell had a  
B trivalent. With 4Bs 30% cells had IV at M1, 60% had II+II and  
in the rest there were two or more univalents. With higher  
numbers of Bs multivalents were formed.

Transinher: during pollen grain mitosis 1 there is directed  
nondisjunction of the standard B and this is due to sticking of  
chromatids in regions on either side of the centromere. With the  
large iso-B the nondisjunction is much less efficient. Crossing  
data are detailed and support the cytological observations. The  
data indicate a high efficiency for the mechanism of transmission  
and multiplication of the Bs.

NOTES:
PolyB: standard fragment, 3 small derivatives by deletion and by  
deletion and inversion and a large iso-B.
Small B from plant 926 has lost the heterochromatic right arm of  
the standard fragment. It fails to undergo nondisjunction at  
pollen grain mitosis and is subject to high levels of meiotic  
elimination. Was not found together with the standard fragment.
Small B from plant 2311 had the same structure as that from 926  
but was found in some plants with the standard fragment. When  
present with the standard fragment it could undergo directed  
nondisjunction at pgm 1, presumably due to the presence of  
a trans-acting controlling element, as in rye. The small Bs fron  
plants 926 and 2311 are probably identical.
Small B from plant 373 has a deletion of the end of the long arm  
of the standard fragment and an inversion of the remaining part  
of the arm making it telocentric. This derivative retains the  
heterochromatic right arm and the capacity for directed  
nondisjunction, even when present alone.
The large iso-B undergoes nondisjunction. It originated from the  
small B of plant 373 (the deficiency-inversion chromosome)  
through centromere misdivision. Shows neocentric activity at A1.

NOTES:
PolyB:standard type (st.acc.) which is 1/4 mean length of As with  
median centromere, and the commonest type. Small B (s.acc.) is a  
class of B type not less than half the size of the standard type.  
Very small B (v.s.acc.) all types smaller than half the st.acc.  
and the smallest appear as dots at mitotic metaphase. Large B  
(l.acc.) is double the size of st.acc.
Meiosis: fold-back pairing of univalent at pachytene, as in  
maize. 60% of univalents, regardless of their number, are on the  
metaphase plate. Univalents left between the poles regularly  
divide at A1 and elimination at telophase I is very low, and very  
few micronuclei in the tetrads. In 2B plants 72.0% cells had  
bivalents, with range from 47-93%. As in 1B plants very few  
univalents are eliminated, and micronuclei in tetrads rarely  
exceed 10%. In 4B plants no multivalents are formed; there is a  
mixture of IIs, II+I and quite a few cells with Is only. Some

TITLE:
The behaviour and possible cytoevolutionary significance of B chromosomes in Dampiera linearis (Angiospermae:Goodeniaceae).

NOTES:
Meiosis:Bs generally univalent at M1 and behaviour variable:  
probability of division at A1 varying from 0.00-0.59. Undivided  
Bs pass randomly into telophase nuclei. In some cells the Bs  
associate together, or with the As, in achiasmate association  
which lapses by M1.
In some plants with 5 and 6 Bs A-bivalent nondisjunction occurs;  
and the nondisjoined bivalents show polarised movement to the  
poles which have high numbers of Bs. Suggested that the pre-M1  
A/B association provides a basis for nonrandom assortment in  
genomically hybrid individuals, and nonreduction associated with  
wholesale nondisjunction induced by high numbers of Bs results in  
the generation of polyploids which are reproductively isolated  
from their diploid progenitors, heterotic and adapted to the  
coastal plain environment (see text for more of this complicated  
story).

Effects of B-chromosomes on recombination in Cylindrotettix obscurus (Leptysminae:Acrididae).

NOTES:
Recombination:analysis of total (T), proximal (P), interstitial  
(I) and distal (D) chiasmata at metaphase 1. B-iso causes  
increase in T and P and has no effect on I and D. Bt leads to  
reduced P with one Bt, then an accumulating increase with higher  
numbers: and the same pattern for T.
Effect of Bt in presence B-iso is to reduce T and P chiasmata in  
a zig-zag fashion, with evens depressed more than odds.

TITLE:
The effect of B-chromosomes of rye on the chromosome association in F1 hybrids Triticum aestivum x Secale cereale in the absence of chromosomes 5B or 5D.

NOTES:
Meiosis in hybrids: T. aestivum var. "Chinese Spring" (monosomic  
5B and 5D respectively) was crossed with S.cereale with and  
without Bs. The resulting nullisomic 5B hybrids exhibited a high  
degree of chromosome association at both 20 and 10 degrees C. The  
Bs reduced association slightly whether 5B was present or not.
In nulli-5D hybrids the Bs raise pairing at 20 degrees compared  
to hybrids with 5D with or without Bs. At 10 degrees C, due to  
the absence of the Ltp gene on 5D, pairing in nulli-5D hybrids is  
low and no effects of Bs is detectable. 
The hypothesis is presented that Bs of rye carry (an) asynaptic  
gene(s) decreasing effective pairing, and (an) independent post  
synaptic gene(s) increasing chiasma frequency at effective  
pairing sites.

TITLE:
The effect of B-chromosomes of rye on chiasma frequency in Triticum aestivum.

NOTES:
Meiosis: effect of rye Bs at M1 in inter-varietal T.aestivum  
hybrid "Chinese Spring" x Lindstrom (with rye Bs), in presence  
and absence of 5D of wheat. Rye Bs have no effect in disomic, but  
slight increase in chiasmata in monosomic-5D at 20 degrees C.  
When 5D absent the increase was more pronounced. Suggested that  
the increase is a consequence of an additive effect of  
post-synaptic gene(s) in rye Bs which locally raise chiasmata in  
As, and of the absence of (a) desynaptic gene(s) of 5D. Even in  
nulli-5D at 10 degrees C, where high pairing was observed, the Bs  
increased pairing; but there was no observable increase in the  
monosomics, which at 10 degrees C did only show a slight  
reduction in pairing.

TITLE:
The effects of derived B-chromosomes on meiosis in Pearl Millet Pennisetum typhoides.

NOTES:
PolyB: standard and deficient Bs acrocentric with the short arm  
consisting of heterochromatin. Deficient B derived from standard  
by loss of two chromomeres from euchromatic long arm. Iso-B  
derived from deficient by centromere misdivision giving an Iso-B  
from the long arm. Iso-B therefore has the least heterochromatin.
Recomb: three kinds of Bs have different effects on mean cell  
chiasma frequencies of As. Deficient had depressing effect, Iso  
enhancing and standard affected the variance but not the mean.  
Combination of B-types give intermediate effects on chiasmata of  
As. Suggested that balance of hetero- and euchromatin of Bs  
causes differential affects on As. Extra euchromatin has  
enhancing effect while heterochromatin is repressing.

NOTES:
Meiosis:meta B is an isochromosome which forms a chiasma when  
univalent. Sometimes the meta B and X associate but segregation  
is random. At A2 the meta always divides normally. The large telo  
migrated precociously at A1 and then divided normally A2. Two Bs  
always form a bivalent and three a bivalent and an univalent. A  
single small telo divides equationally A1 and two may form a  
bivalent. At A2 each small telo divides equationally.

NOTES:
Aegilops speltoides with and without Bs used in hybrids with  
tetraploid wheats Triticum dicoccoides (AABB), T. dicoccum  
(AABB), T. durum (AABB) and T. araraticum (AAGG). Hybrids with Bs  
showed extensive univalent formation, whereas in those without  
the pairing was considerable. Some minor A-chromosome background  
effects were also observed. Since the Bs did not cause asynapsis  
(or desynapsis) of homologous chromosomes in Ae. speltoides the  
reduced pairing in the hybrids is probably due to failure of  
homoeologous associations. Concluded that there is little  
homology between Ae. speltoides and tetraploid wheats of AABB and  
AAGG genomic constitution.

TITLE:
Interaction between rye B-chromosomes and wheat genetic systems controlling homoeologous pairing.

NOTES:
Recomb: the interactive effect on homoeologous pairing of rye  
B-chromosomes with the absence of both pairing suppressor  
(3A,3D,5B) and promotor (3B,5A,5D) chromosomes of common wheat  
(Triticum aestivum L.) was analyzed by comparison of pairing at  
M1 of 27-, 27 +2B-, 28- and 28 + 2B-chromosome plants. These  
plants were obtained from crosses between the respective wheat  
monosomics (2n=41) and rye plants (Secale cereale) carrying or  
not carrying the Bs (2n=14 or 14 + 2Bs). The effect of the rye Bs  
on pairing depended on the function of the wheat chromosome  
missing in the appropriate hybrids, i.e. rye Bs have a suppressor  
effect on pairing when the pairing suppressing wheat chromosomes  
3A,3D or 5B are absent, while they behave as promotors when the  
pairing promotor chromosomes 3B,5A or 5D are absent.

Pops. B-frequency at local level and variation in the frequency

small area of SW Oklahoma and Texas between 1974-1987. Chromosome  
numbers of 1224 plants counted at meiosis: 15.8% plants with Bs,  
less than 1% had 3 or 4 Bs and none had more than 4 Bs.   
Frequency of plants with Bs among all sites ranged from 0-33% and  
from 0-25% in sites separated by only a hundred metres; large  
differences in sample size occurred.  Even at the subsite level  
large differences in frequencies of plants with Bs were found.   
Within single sites B-frequency was not constant through time;  
the pattern of change differed among subsites within populations.  
In some cases the frequency went to zero.  No correlations  
between environmental parameters and b frequency were documented.

TITLE:
The heterogeneity of B-chromosome DNA: no evidence for a B-chromosome specific repetitive DNA correlated with B-chromosome effects on meiotic pairing in the Triticinae.

NOTES:
Molecular: compositional heterogeneity of DNA of As and Bs  
compared to elucidate mechanism of B disruption of meiotic  
pairing in species hybrids. Comparisons of % heterologous  
association after DNA/DNA hybridisation at Cot 10-2 (highly  
repetitive) and Cot 100 (moderately repetitive), and comparisons  
of nucleotide base divergence (Delta Tms) and thermal elution  
profiles of homologous and heterologous duplexes, show that  
genotypes of Aegilops species having many Bs, do not carry  
additional families of repetitive DNA exclusive to Bs. Neither  
the presence of Bs nor the direction of DNA/DNA hybridisation  
affect the above parameters.  No cryptic DNA satellites were  
revealed in A- and B-chromosome DNA after sedimentation in  
actomycin D-CsCl gradients; and there were no significant  
differences in buoyant densities of main-band DNA.  Mean melting  
temperatures (Tm); transition temperatures (delta T) and numbers  
and positions of peaks of dissociating DNA fractions in profiles  
of differential melting curves of native DNAs were similar in  
strictly comparable denaturation conditions.  One small AT-rich  
(< 5%) DNA fraction correlated with Bs was revealed (but no  
corresponding fraction associated with mutica Bs).  All above  
discussed in relation to origin of Bs and the origin of the  
diploidising system in hexaploid T.aestivum.

consistent (A-T)n- rich DNA associated with the DNA of genotypes  
of Ae. speltoides with B-chromosomes, observed as a discrete peak  
in derived denaturation profiles, could contribute to the small  
reduction in G + C% composition of total DNA, reflected in lower  
Tms and lighter buoyant densities of B-chromosome carrying  
plants.  However, this small DNA fraction cannot account for all  
of the additional 30% B-chromosome DNA in 6B chromosome  
individuals.  The overall similarities in the melting  
characteristics of the DNA extracted from Ae. speltoides (with or  
without Bs), Ae. mutica (with or without Bs), and Triticum  
aestivum show that the greater proportion of B-chromosome DNA  
appears to contain a spectrum of sequences not unlike  
A-chromosome DNA of the three species.

Interpopulation variation in the satellite DNA from grasshoppers with B-chromosomes.

Molecular:on CsCl gradient the DNA from individuals with Bs

in individuals without Bs.  This was shown in several  
populations.  This B DNA contains 28% repeated and 72% unique  
sequences as determined by hydroxyapatite chromatography,  
compared with 10% and 905 for the A-genome.  This was shown in  
two populations.  The repeated sequences of the B DNA have no  
homology, as shown by lack of hybridisation between labelled  
C-DNA transcribed from B DNA of different populations.  This lack  
of homology was also suggested by density differences between  
B-satellites in CsCl gradients.  There was no sequence homology  
between the satellite B DNA and the main peak nuclear DNA.

NOTES:
Transinher: all 4 megaspore nuclei produced by meiosis in emc  
take part in the formation of the embryo sac: (i) one  
nucleus remains near micropylar end and the other three migrate  
to chalazal end; (ii) at 1st mitosis the three chalazal megaspore  
nuclei fuse; (iii) the two successive post-meiotic divisions  
produce 4 haploid nuclei on micropylar side and 4 triploid nuclei  
on chalazal side; (iv) gives embryo sac with 3-celled haploid egg  
apparatus, 3 triploid antipodals and 2 polar nuclei (one haploid  
and one triploid).  Micropylar end of developing embryo sac is  
broad and round - i.e. asymmetrical spindle.
The Bs lying on micropylar side 63.7%, chalazal side 13.0% and MI  
plate 23.3% in emcs.  If all Bs outside the MI plate pass  
undivided to the micropylar pole, and the Bs on the plate to  
either pole equally, then at least 75.4% of micropylar nuclei  
will include the B.  Actually at AI, MII, AII, the post-meiotic  
1st and 2nd divisions, 80.0% of micropylar nuclei showed n=12 +  
1B.  This value coincides exactly with progeny analysis which  
gave 2n=24 + 1B and 2n=24 in proportion 80:20.

TITLE:
On the mechanism of chromatin loss induced by the B chromosome of maize.

NOTES:
Knob loss: Konobbed regions of the As frequently eliminated at  
2nd pgm with 2 or more Bs.  Little or no loss with 1B, and rate  
not increased with more than 2B.  Bs from unrelated strain are  
equally effective.  Knobbed A-chromosomes 3,5 and 9 all interact  
with B to give loss.  Chromosomes with large knobs more  
frequently broken than those with smaller knobs and knobless ones  
show negligible loss.  Modifying genes can affect the rate of  
loss.  Two knobbed heterologous chrs undergo simultaneuos loss  
more often than expected from independent events.  Data suggest  
that joint loss occurs in competent cells and that preferential  
assortment of the two deficient chrs to specific poles is  
unlikely.  Bs and deficient chrs assort independently at anaphase  
of pgm2.  Genetic data from crosses with marker genes in both  
arms of chr 3 show that breakage of the postulated dicentric  
bridge does not occur solely at the centric region since a  
variety of deficient chrs were recovered.  Ndj of Bs and  
elimination of knobbed chromatin occur at pgm2.  The arguement is  
advanced that the two phenomena result from faulty replication of  
heyerochromatic segments.  The psotion of the nonreplicating  
segment in the two kinds of chrs determines whether ndj or  
breakage takes place.  Suggested that all of the reported effects  
of the Bs can be accounted for if the B is a parasite having no  
genetic function other than controlling the replication of its  
proximal heterochromatic knob and increasing the ability of  
B-containing sperm cells to compete successfully for  
fertilization of the egg.

NOTES:
Meiosis: as in other holocentric systems meiosis is inverted, the  
first division equational and the second reductional, and in  
mealy bugs meiosis is uniquely modified in the males.  These have  
the same diploid number as females but one haploid set (paternal)  
becomes heterochromatic at blastula and remains so throughout  
development.  During meiosis I both heterochromatic and  
euchromatic chromosomes simply divide mitotically; during the  
second the heterochromatic and euchromatic stes segregate to  
opposite poles.  There are thus four products of division, two  
heyerochromatic and two euchromatic; the heterochromatic  
derivatives degenerate and the euchromatic derivatives proceed to  
form sperm.
At oogenesis the Bs remain unassociated and divide equationally  
during the first division; during the second, they pair and  
disjoin.  Pairing is usually accomplished by twos so that an  
unpaired B is found whenever an odd number, or only one, is  
present; the unpaired entity is twice as likely to go to the  
second polar body as to the egg.
The normal spermatogenesis is highly modified with the paternal  
heterochromatic set being eliminated from the genetic continuum;  
and during this sequence the Bs are fully heterochromatic up  
until late prophase I.  They then undergo a sharp change in  
pycnosis and become negatively heteropycnotic.  In the second  
meiotic division they usually segregate with the maternal  
euchromatic set.  Their behaviour thus becomes an accumulation  
mechanism since an unreduced number,or nearly that, is  
transmitted by the males.

TITLE:
Phylogenetic relationships of Aegilops mutica Boiss with the diploid species of congeneric Aegilops-Triticum complex, based on the new method of genome analysis using its B-chromosomes.

NOTES:
F1 hybrids of Ae. mutica with 9 other Ae. species (bicornis, ì
sharonensis, longissima, speltoides, squarrosa, caudata, comosa, ì
uniaristata, umbellata) and one species of Triticum (monococcum).
F1 with 2Bs from crosses of Ae. bicornis, longissima, caudata, ì
comsa, umbellata, and T. monococcum show low frequency A-pairing.  ì
In contrast 2B hybrids from crosses of Ae. speltoides and ì
squarrosa showed a higher frequency of A-pairing, and with ì
speltoides it varied widely and did not differ from 0B hybrids: ì
so the genome of mutica is almost homologous with those of ì
speltoides and sqarrosa, and homologous with other species where ì
Bs suppress pairing in the F1.
In some crosses single telo Bs were found, probably due to ì
misdivision, and these give indication of dosage effects of Bs as ì
they give intermediate levels of pairing in F1s.  In other ì
hybrids single meta Bs were found, and also evidence for telos of ì
both arms and heterogeneity of effects.
