Brazilian Archives of Biology and Technology, 2008 The Passifloraceae is represented by species of tropical and subtropical origin. The Passiflora is the richest genus with approximately 450 species, 200 of them being native to Brazil. Recent karyological studies have reported the basic chromosome number

Frontiers in Plant Science, 2018 Meiosis, the type of cell division that halves the chromosome number, shows a considerable degree of diversity among species. Unraveling molecular mechanisms of the meiotic machinery has been mainly based on meiotic mutants, where the effects of a change

A sex-ratio meiotic drive system in Drosophila simulans. II: an X-linked distorter. [PDF]
PLoS Biology, 2007 The evolution of heteromorphic sex chromosomes creates a genetic condition favoring the invasion of sex-ratio meiotic drive elements, resulting in the biased transmission of one sex chromosome over the other, in violation of Mendel's first law.

A simple model for the influence of meiotic conversion tracts on GC content. [PDF]
PLoS ONE, 2011 A strong correlation between GC content and recombination rate is observed in many eukaryotes, which is thought to be due to conversion events linked to the repair of meiotic double-strand breaks. In several organisms, the length of conversion tracts has

PLoS Genetics, 2018 Sister kinetochores are connected to the same spindle pole during meiosis I and to opposite poles during meiosis II. The molecular mechanisms controlling the distinct behavior of sister kinetochores during the two meiotic divisions are poorly understood.

Reproductive characteristics of citrus rootstocks grown under greenhouse and field environments [PDF]
Crop Breeding and Applied Biotechnology, 2013 The aim of the present study was to evaluate the possible effect of environmental factors on meiosis, meiotic index, pollenviability and in vitro germination of pollen from stock plants of the rootstocks Trifoliate, ‘Swingle’, ‘Troyer’, ‘Fepagro C13 ...

MEIOTIC BEHAVIOR OF ASYMMETRIC DYADS IN THE MALE DROSOPHILA [PDF]
Genetics, 1973 ABSTRACT Crossing over in the interstitial region of the heterozygous V4 translocation in Drosophila melanogaster generates asymmetric dyads each consisting of a shorter and a longer chromatid It was shown previously that in the female the shorter is recovered preferentially (ZIMMERING 1955); the present work suggests that the same ...
