Strong gender differences in reproductive success variance, and the times to the most recent common ancestors [PDF]

open access: yesJournal of Theoretical Biology 310, 43-54 (2012), 2012

These TMRCAs have special demographic implications because mtDNA is transmitted only from mother to child, and NRY from father to son.
