The Genetic Basis of Male Infertility
2.1 Errors in Synapsis 2.1.1 The Asynaptic Phenotype and Sterility It is likely that
asynapsis (synaptic failure) can be linked to more cases of male sterility than any
other aberrant meiotic defect (Chandley 1979; Tiepolo et al. 1981; Chandley ...
The recognition of desynapsis, because the later stages of prophase are more
readily analyzed, is often easier than the recognition of the alternative condition
of asynapsis. For this reason, it is perhaps not surprising that most of the genes ...

Nuclear Cytology in Relation to Development
Asynapsis A prerequisite for pairing (synapsis) is the homology of chromosomes
or chromosome segments. When no homology exists between the chromosomes
of the two parents, as in interspecific or intergeneric hybrids, no synapsis occurs ...
In heterozygous condition, sal/+, the puffs are active on the homolog from the
normal strain when this asynapsis does not occur. These three puffs are
inactivated in sal as result of a single mutation (Levine and Van Valen, 1962;
Gersh, 1972a ...

Fertility and Chromosome Pairing
The asynapsis seen in the inversion carrying bivalent No. 1 of man may primarily
arise from the presence of a large heterochromatic block delaying synapsis.

between ...

Citrus Genetics, Breeding and Biotechnology
Vardi and Spiegel-Roy (1981) postulated that asynapsis was controlled by a
single recessive gene because about a quarter of progeny arising from self-
pollination of 'Wilking' showed asynapsis. Nakano et al. (2000) found DNA
markers ...
tics is always lower than that of synaptics. We are inclined to conclude that sperm
produced by an individual of asynaptic biotype carry different numbers of genes
dealing with asynapsis and that a certain number of them is required for the ...

Production of Potatoes from True Seed
If the asynaptic clone is female sterile, a clone heterozygous for the asynapsis
gene might be used. Then in sib F2 or BC-generations genotypes being
recessive for both asynapsis and FDR may occur. It is still obscure whether such
genotypes ...

Evolution of the House Mouse
The pachytene checkpoint is known to monitor unrepaired DSBs and/or
chromosome asynapsis in yeast (Roeder and Bailis, 2000). Though the
molecules involved in monitoring in the pachytene checkpoint have not been
identified in mice, ...

Anopheline Species Complexes in South and South-East Asia
Asynapsis in polytene complements in hybrids is used as one of the criteria in
determining species status. The degree of asynapsis may vary, and thus has to
be used with caution. In hybrids between members of the Culicifacies Complex,
the ...
