TL;DR: The first genome-wide identification and characterisation of sexually antagonistic SNPs in a population of D. melanogaster is reported, providing unprecedented insights into the biology and evolution of sexual antagonism, and open opportunities for more detailed studies of constraints on sex-specific adaptation and mechanisms that resolve them.

TL;DR: New research documents this process in a bacterial system and highlights remarkable parallels to the evolution of sexual dimorphism and argues that their approach can aid the understanding of adaptive conflicts between the sexes.

TL;DR: It is shown that for sites longer than 1 nucleotide, expression polymorphism is maintained only when intermediate expression levels are deleterious to both sexes, and that, in a regulatory cascade,expression polymorphism tends to become displaced over evolutionary time from the target of SA selection to upstream regulators.

TL;DR: It is proposed that antagonistic variation accumulates due to constraints on the resolution of sexual conflict over protein coding sequences, thus contributing to the long-term maintenance of heritable fitness variation.
