Journal of molecular evolution - 1 Dec 1999

Abstract excerpt
Because avian females are heterogametic, the reverse of mammals, avian sex chromosomes undergo significantly different patterns and numbers of DNA replications than do those in mammals. This makes the W (female-specific) and the Z chromosomes an excellent model system for the study of the replicative division hypothesis, which purports that DNA substitution rate is determined by the number of germline...
