Female preference for male courtship effort drives the evolution of male mate choice
(English)Manuscript (preprint) (Other academic)
The evolution of male mate choice is constrained by costs of choice in species with a male-biasedoperational sex ratio. Previous theoretical studies have shown that significant male benefits ofmale choice are required, e.g., by mating with more fecund females, in order for these costs to beoffset and the male preference to spread. We consider the possibility that another type of effectmay favour the evolution of male mate choice by exploring a series of population genetic models.We find that a male mating preference can spread when males court preferred females more andfemales prefer, and thus are more likely to mate with, males who court more. Further, viability orfecundity selection on the preferred female trait is a much more powerful determinant of the fateof the female trait than is the presence of the male preference. We confirm that indirect selectionon the male preference due to linkage disequilibrium between the female trait and malepreference alleles can affect the evolution of the male trait, however, these effects are slight incomparison to direct selection on the male trait.
