Paul Andersen explains how X inactivation works in mammals. This process was first described by Mary Lyon. Each cell in a female will have on activated and one inactivated X chromosome. This explains why almost all calico cats are female.

Discover the role Y chromosomes can play in the development of genealogies. A short animation describes how Y chromosomes are passed among generations and the information they reveal about ancestry.
