Interpretive Summary:

Technical Abstract: In this study we used microsatellite variable repeat regions and other molecular markers to indicate multiple insemination of a HIFA queen in a polygyne mound. By genotyping the mound’s queens and the contribution of sperm found in their spermathecae, we found unexpectedly high numbers of alleles for specific loci. We also show that newly inseminated queens of both social forms sometimes contain sperm with a higher than expected number of alleles for these loci, suggesting that this is not an isolated case for polyandry, but may happen with regular frequency.
