The frequencies of two alleles at a cathodal malate dehydrogenase locus in populations of A. rudis were studied in 47 colonies from three localities in Georgia and one in New Jersey. The male gene frequencies of the New Jersey and one Georgia locality differ significantly. All the queens at one Georgia locality were heterozygotes. This genotypic distribution differs strongly from that of the workers, in which approximately equal numbers of heterozygotes and homozygotes were found. The heterozygote excess among queens but not their worker progeny suggests differential selection between these castes. This study also shows that rudis colonies consist of a single, once-mated queen and her worker progeny.
对来自佐治亚州三个地点和新泽西州一个地点的47个群体中的粗角蚁苹果酸脱氢酶阴极位点的两个等位基因频率进行了研究。新泽西州和佐治亚州一个地点的雄性基因频率有显著差异。佐治亚州一个地点的所有蚁后都是杂合子。这种基因型分布与工蚁的分布有很大不同，在工蚁中杂合子和纯合子的数量大致相等。蚁后中杂合子过剩，但其工蚁后代中并非如此，这表明这些蚁型之间存在差异选择。这项研究还表明，粗角蚁群体由一只单次交配的蚁后及其工蚁后代组成。
