Researchers have found DNA evidence that polygyny, the practice among males of siring children with multiple female partners at the same time or successively, has led to an excess of genetic diversity on the X chromosome relative to the autosomes. Details are published Sep. 26 in the open-access journal PLoS Genetics.
