Sex-Specific Selection and the Evolution of Between-Sex Genetic Covariance

Kin selection models for the co-evolution of the sex ratio and sex-specific dispersal

We investigate the co-evolutionary relationship between sex-ratio bias and sex-specific dispersal behaviour using an inclusive fitness approach. We consider two models: (i) DDM, in which dispersal of both sexes occurs before mating; and (ii) DMD, in which male dispersal precedes mating and female dispersal follows mating. Under DDM, at equilibrium, there is no bias in either the sex ratio or th...

Sex, Mate Selection, and Evolution

Simulations of the evolution of populations of diploid organisms showed that mate selection strategies which selected for “good genes” and strategies based on assortative mating, confer a much higher average fitness and higher evolutionary stability to populations than random mating. This advantage was more conspicuous the more genes per organism were simulated and the more genes were involved ...

Sex - Biased Gene Expression Resolves Sexual Conflict through the 1 Evolution of Sex - Specific Genetic Architecture

attitudes about sex selection and sex preference in iranian couples referred for sex selection technology

background: gender preference is prevalent in some communities and using medical techniques to choose the baby’s sex may cause the gender discrimination and gender imbalance in communities. therefore, evaluating the gender preferences and attitudes towards using sex selection technologies seems to be necessary. methods: this cross-sectional study was conducted in avicenna fertility center. part...
