Substitution rate heterogeneity and the male mutation bias.

Abstract excerpt

Germline mutation rates have been found to be higher in males than in females in many organisms, a likely consequence of cell division being more frequent in spermatogenesis than in oogenesis. If the majority of mutations are due to DNA replication error, the male-to-female mutation rate ratio (alpha(m)) is expected to be similar to the ratio of the number of germ line cell divisions in males and females (c), an...
