Sex differences in chiasma distribution along two marked mouse chromosomes: differences in chiasma distribution as a reason for sex differences in recombination frequency

Sex differences in recombination

One of the stronger empirical generalizations to emerge from the study of genetic systems is that achiasmate meiosis, which has evolved 25-30 times, is always restricted to the heterogametic sex in dioecious species. usually the male. Here we collate data on quantitative sex differences in chiasma frequency from 54 species (4 hermaphroditic flatworms, 18 dioecious insects and vertebrates and 32...

The two-locus model with sex differences in recombination.

The criteria for stability of the equilibrium with D=0 are obtained for the two locus model with multiplicative or symmetric fitnesses when the recombination values in males and females are different. It is shown that if r is defined to be equal to the average of the recombination values in males and females, then the criteria are exactly the same as in the standard two locus model.-The equilib...

Study of Share of Unintentional Accidents in Sex Differences of Mortality in Iran, 2006-2015

Background and objectives: Considering the high contribution of unintentional accidents to mortality, particularly in males in Iran, and their changes over the last decade, a study was conducted to review the share of deaths due to unintentional accidents in sex difference in life expectancy at birth in the country over the last decades. Methods: The mortality data for the years 2006 to 2015...

Sex differences in interaction style as a product of perceived sex differences in competence.

Males' and females' interaction styles were observed while they worked in four-person, mixed-sex groups on a discussion task. In some groups, members were only given information about each others' names and gender. In this circumstance, men were perceived by themselves and other group members to be higher in competence than women. Further, men engaged in a greater amount of active task behavior...
