THE STRENGTH OF INDIRECT SELECTION ON FEMALE MATING PREFERENCES

摘要: An important but controversial class of hypotheses concerning the evolution female preferences for extreme male mating displays involves “indirect selection.” Even in absence direct fitness effects, preference males with high overall can spread via a genetic correlation that develops between alleles and genotypes. Here we develop quantitative expression force indirect selection (i) applies to any behavior, (ii) is relatively insensitive underlying genetics, (iii) based on measurable quantities. In conjunction limited data now available, it suggests evolutionary generated by weak absolute terms. This finding raises possibility genes may often be more than selection, quantities identified our model are needed decide question.
