Abstract excerpt

Sex chromosomes play a role in many important biological processes, including sex determination, genomic conflicts, imprinting, and speciation. In particular, they exhibit several unusual properties such as inheritance pattern, hemizygosity, and reduced recombination, which influence their response to evolutionary factors (e.g., drift, selection, and demography). Here, we examine the evolutionary forces driving X...
