Maintenance of Sperm Variation in a Highly Promiscuous Wild Bird

Calhim, Sara; Double, Michael; Margraf, Nicolas; Birkhead, Tim R; Cockburn, Andrew

Description

Postcopulatory sexual selection is an important force in the evolution of reproductive traits, including sperm morphology. In birds, sperm morphology is known to be highly heritable and largely condition-independent. Theory predicts, and recent comparative work corroborates, that strong selection in such traits reduces intraspecific phenotypic variation. Here we show that some variation can be maintained despite extreme promiscuity, as a result of opposing, copulation-role-specific selection...[Show more]
