The increased capacity of DNA sequencing has significantly advanced our understanding of
the phylogeny of birds and the proximate and ultimate mechanisms molding their genomic …

Sexual conflict occurs when selection acts in opposing directions on males and females.
Case studies in both vertebrates and invertebrates indicate that sexual conflict maintains …

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 …

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 …

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 …

Males and females of the same species share the majority of their genomes, yet they are
frequently exposed to conflicting selection pressures. Gene regulation is widely assumed to …

Sex chromosomes have evolved repeatedly across the tree of life and often exhibit extreme
size dimorphism due to genetic degeneration of the sex-limited chromosome (eg the W …

Sexually antagonistic (SA) genetic variation—in which alleles favored in one sex are
disfavored in the other—is predicted to be common and has been documented in several …

Sex-differential selection (SDS), which occurs when the fitness effects of alleles differ
between males and females, can have profound impacts on the maintenance of genetic …
