Origins and significance of preference for rare/novel male morphs: Trinidadian guppies as a case study.

Abstract excerpt

Recent evidence suggests that negative frequency-dependent selection may be a pervasive explanation for the high genetic variation observed in ecologically important traits. Female mating preference for rare/novel male phenotypes is one process that can generate frequency-dependent selection and has been well documented in some highly polymorphic systems. However, two major gaps in the literature limit the...
