Effect of inbreeding on genetic relatedness

Open full text 103 citations

Abstract

The effect of inbreeding on genetic relatedness (intragroup genotypic correlation) is examined in several models with special emphasis on social Hymenoptera (all male-haploid) living in nests. Inbreeding takes place in the form of intranidal matings, and the models are developed for polygyny (several females reproducing in one nest) and polyandry. The latter models are also developed for diploid populations. The equations derived here are applied to the population data from the ant Formica exsecta.
