Chromosome Research, 1995
The questions of whether closely spaced crossovers could be misidentified as single chiasmata or could cancel out each other and whether exchange could occur without chiasma formation were examined in Locusta migratoria. Monochiasmate bivalents that showed differential sister chromatid staining following bromodeoxyuridine incorporation were screened ...

Experiments on Chiasmata and Nondisjunction in Mice
1981Meiosis in the female mammal has both an intrinsic interest and a practical one. Intrinsically, it is interesting because of the complexity of its control and because the whole of its prophase, including recombination of linked genes by crossing over, occurs in utero and is followed by a long dormant stage before final maturation of the ova, in ...

1. Chiasma frequency has been studied in male mice; fifty diplotene and fifty-six diakinesis counts were recorded. 2. The sex chromosomes differ from the autosomes during earlier stages of prophase, preceding them in contraction and in appearance and movement of chiasmata. 3.

Recombination and chiasmata: few but intriguing discrepancies
Genome, 1996The paradigm that meiotic recombination and chiasmata have the same basis has been challenged, primarily for plants. High resolution genetic mapping frequently results in maps with lengths far exceeding those based on chiasma counts. In addition, recombination between specific homoeologous chromosomes derived from interspecific hybrids is sometimes ...

[Terminalization of chiasmata. Analysis of the phenomenon].
Genetika, 1995On the basis of my own and published data, a conclusion was made that meiotic terminalization of chiasmata, which was postulated by Darlington, does not occur. The chiasmata remain in the sites where they appear, until the disjunction of homologous chromosomes in meiotic anaphase I.
