Consequently, they allow individual behaviour to exist with regard to synapsis and chiasma formation in each combination of chromosome arms and genomes, though "the pattern of genomic affinity" must be the same for the two arms belonging to the same chromosome (Crane & Sleper, 1989a).
Whereas B-chromosomes have been shown to influence chiasma formation in some species and hybrids, they have no apparent effect on meiosis in others.
chiasma formation, caused by B-chromosomes should be correlated to the degree of homology.
