Evolutionary potential for genomic islands of sexual divergence on recombining sex chromosomes

Summary Differentiated sex chromosomes are thought to develop through the accumulation of polymorphisms at loci subject to opposing selection between males and females, and/or between haploids and diploids. As sex chromosomes differentiate, reduced recombination becomes favored between selected loci and the sex‐determining region, strengthening genetic associations between alleles favored in a sex and the corresponding sex chromosome. Here a...
