| high levels of diploid male production in a primitively eusocial bee (hymenoptera: halictidae). | 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 propor ... | 2001 | 11903558 |
