Consequences of genetic incompatibility on fitness and mate choice: the male point of view

摘要: Hymenopterans under single-locus complementary sex determination (sl-CSD) face inbreeding costs due to this mode. Under sl-CSD, homozygote eggs at the sl-CSD locus usually develop into unviable or sterile diploid males. Production of such costly males increases when sib-mating happens because related individuals share half their genome. In hymenopteran Venturia canescens (a solitary parasitoid wasp), are sterile, leading fitness through genetic incompatibility between parents. Whereas producing and behavioural strategies that would reduce have been studied in females, potential faced by not. Here, we aimed investigate endure after a single tested whether they ability avoid kin recognition. Our results show reduced (i.e. produce fewer daughters) mating with sibs. We also distinguish non-sib sib females kin). They use chemical marks emitted discriminate from non-kin. discuss evolution recognition context mate choice for compatibility. © 2014 The Linnean Society London, Biological Journal Society, 2015, 114, 279–286.
