Additive genetic variance (VA) reflects the potential for evolutionary shifts and can be low for
some traits or populations. High VA is critical for the conservation of threatened species …

As the evolutionary interests of males and females are frequently divergent, a trait value that
is optimal for the fitness of one sex is often not optimal for the other. A shared genome also …

Males and females share many traits that have a common genetic basis; however, selection
on these traits often differs between the sexes, leading to sexual conflict,. Under such sexual …

Sex differences in complex traits are suspected to be in part due to widespread gene-by-sex
interactions (GxSex), but empirical evidence has been elusive. Here, we infer the mixture of …

Teleost fishes exhibit complex sexual characteristics in response to androgens, such as fin
enlargement and courtship display. However, the molecular mechanisms underlying their …

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

Many animal taxa show frequent and rapid transitions between male heterogamety (XY) and
female heterogamety (ZW). We develop a model showing how these transitions can be …

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 …

Sexual dimorphism is one of the most prevalent, and often the most extreme, examples of
phenotypic variation within species, and arises primarily from genomic variation that is …
