Females prefer the scent of outbred males: good-genes-as-heterozygosity?

BMC evolutionary biology - 16 May 2009

Ilmonen Petteri, Stundner Gloria, Thoss Michaela, Penn Dustin J

Abstract excerpt

BACKGROUND: There is increasing interest to determine the relative importance of non-additive genetic benefits as opposed to additive ones for the evolution of mating preferences and maintenance of genetic variation in sexual ornaments. The 'good-genes-as-heterozygosity' hypothesis predicts that females should prefer to mate with more heterozygous males to gain more heterozygous (and less inbred) offspring....
