The Genomic War Between the Sexes
Sexually antagonistic selection (SAS), which occurs when different alleles are favored in females and males. While SAS is key to many key evolutionary processes, its prevalence in the genome is largely unknown. We use a new method to show that SAS acts on a very large number of sites across the human genome. It contributes to human mortality, and involves tradeoffs between survival and fecundity that work in converse ways in females and males. In nonhuman animals, SAS may be important to determining the sex ratio, and to the origin and subsequent evolution of sex chromosomes.
