Dosage-sensitive functions in embryonic development drove the survival of genes on sex-specific chromosomes in snakes, birds, and mammals
2020-07-11
Abstract excerpt
Different ancestral autosomes independently evolved into sex chromosomes in snakes, birds, and mammals. In snakes and birds, females are ZW, while males are ZZ; in mammals, females are XX and males are XY. While X and Z chromosomes retain nearly all ancestral genes, sex-specific W and Y chromosomes suffered extensive genetic decay. In both birds and mammals, the genes that survived on sex-specific chromosomes are...
