在单基因座互补性别决定（sl-CSD）下，二倍体雄性产生自在性别决定基因座处纯合的受精卵。二倍体雄性实际上是不育的，因此它们的生产产生了昂贵的遗传负荷。利用等位酶电泳，大量的二倍体男性在自然种群中检测到的reactively eusocial蜜蜂，Halictus poeyi Lepeletier收集在南部和中部佛罗里达在2000年5月。估计的比例二倍体是男性的范围从9.1%到50%，而匹配交配的频率范围从18.2%到100%。性别决定基因的有效等位基因数为2 ~ 11个，平均为5个。有效种群大小为19.6 ± 2.5SE。这些数据被解释在光的佛罗里达和H的社会生物学/种群动态的地理历史。poeyi。
Under single locus complementary sex determination (sl-CSD), diploid males are produced from fertilized eggs that are homozygous at the sex-determining locus. Diploid males are effectively sterile, and thus their production generates a costly genetic load. Using allozyme electrophoresis, a large number of diploid males were detected in natural populations of the primitively eusocial bee, Halictus poeyi Lepeletier collected in southern and central Florida during May 2000. Estimates for the proportion of diploids that are male ranged from 9.1% to 50%, while the frequency of matched matings ranged from 18.2% to 100%. The effective number of alleles at the sex-determining locus ranged from two to 11, with an average of five alleles. The effective population size of Halictus poeyi was estimated to be 19.6 ± 2.5 SE. These data are interpreted in the light of the biogeographic history of Florida and the social biology/population dynamics of H. poeyi.
