The profound differences in gene expression between the sexes are increasingly used to
study the molecular basis of sexual dimorphism, sexual selection and sexual conflict …

Sexual selection has the potential to decrease mean fitness in a population through an array
of costs to nonsexual fitness. These costs may be offset when sexual selection favors …

The evolution of sexual dimorphism is constrained by a shared genome, leading to 'sexual
antagonism', in which different alleles at given loci are favoured by selection in males and …

Sexual dimorphism is a substantial contributor to the diversity observed in nature, extending
from elaborate traits to the expression level of individual genes. Sexual conflict and sexually …

Sexual dimorphism results from sex-biased gene expression, which evolves when selection
acts differently on males and females. While there is an intimate connection between sex …

Sexual antagonism, whereby mutations are favourable in one sex and disfavourable in the
other, is common in natural populations, yet the root causes of sexual antagonism are rarely …

Genes with sex-biased expression show a number of unique properties and this has been
seen as evidence for conflicting selection pressures in males and females, forming a genetic …

Background Stress and anxiety-related behaviors are seen in many organisms. Studies
have shown that in humans and other animals, treatment with selective serotonin reuptake …

How common is balancing selection, and what fraction of phenotypic variance is attributable
to balanced polymorphisms? Despite decades of research, answers to these questions …

The maintenance of genetic variance in fitness represents one of the most longstanding
enigmas in evolutionary biology. Sexually antagonistic (SA) selection may contribute …
