Abstract

Researchers sampled 48 societies cross-culturally to study the genetic survival of male homosexual preference, which is argued to be deleterious in nature due to its fertility costs. The researchers test for a sexually antagonistic factor that would produce a pleotropic advantage, such as male homosexual preference increasing the reproduction of sisters. Utilizing theoretical models, researchers assert that the survival of male homosexual preference is a result of the positive association between social stratification and discriminate female hypergyny due to selection for attractiveness in females.
