Degeneration of a nonrecombining chromosome.

Science (New York, N.Y.) - 14 Jan 1994

Rice W R

Abstract excerpt

Comparative studies suggest that sex chromosomes begin as ordinary autosomes that happen to carry a major sex determining locus. Over evolutionary time the Y chromosome is selected to stop recombining with the X chromosome, perhaps in response to accumulation of alleles beneficial to the heteroga...
