Abstract excerpt
Sex chromosomes may provide a context for studying the local effects of mutation rate on molecular evolution, since the two types of sex chromosomes are generally exposed to different mutational environments in male and female germ lines. Importantly, recent studies of some vertebrates have provided evidence for a higher mutation rate among males than among females. Thus, in birds, the Z chromosome, which spends...
