Variation in the peacock's train shows a genetic component.

Genetica - 1 Jan 2009

Petrie Marion, Cotgreave Peter, Pike Thomas W

Abstract excerpt

Female peafowl (Pavo cristatus) show a strong mating preference for males with elaborate trains. This, however, poses something of a paradox because intense directional selection should erode genetic variation in the males' trains, so that females will no longer benefit by discriminating among males on the basis of these traits. This situation is known as the 'lek paradox', and leads to the theoretical...
