Hardy–Weinberg ratios and rare male mating advantage

Abstract

PETIT1 and others have shown that in a variety of Drosophila species the mating success of male genotypes is often dependent on their frequency in the population. This frequency-dependent mating effect seems to be relatively unimportant in females, and by favouring rare male genotypes represents a possible mechanism by which genetic variation can be maintained in a population. Whether or not this form of selection is wide-spread in natural populations is unknown, although, in the laboratory at least, it has been shown that the phenomenon occurs in insects other than Drosophila2,3.
