Abstract
Using four highly polymorphic microsatellite markers (12–28 alleles), we gentoyped workers from 63 colonies ofPogonomyrmex occidentalis. Colonies have a single, multiply mated queen, and an average number of 6.3 patrilines per colony. Colony growth was measured over an 8‐year period in the study population. Intracolonial relatedness and colony growth are correlated negatively, indicating a substantial fitness benefit to multiple mating.Keywords
