Heritable variation in the timing of spermatophore removal, a mechanism of post-copulatory female choice in crickets.

Abstract excerpt

Female crickets can exert post-copulatory mating preferences by prematurely removing a male's spermatophore after copulation, which terminates sperm transfer. Although most models of sexual selection assume that female mating preferences are heritable, there has been little work addressing genetic variation underlying post-copulatory mate choice. We used a paternal half-sib design, in which different males were...
