Genomic studies of sex differences : On mutations, recombination, and sexual antagonism in songbirds
Many organisms have separate sexes, i.e., males and females. The presence of separate sexes causes sex-specific selection regimes and sexual antagonism, which can lead to sex differences in morphology, physiology, and behaviours. Sex and sex differences can be genetically governed and regulated by a pair of sex chromosomes (e.g., X and Y, or Z and W), on which there often are regions without recom
