证明单倍二倍体在膜翅目（蜜蜂、黄蜂和蚂蚁）真社会性进化中的重要性需要估计四个参数：合作个体之间的相关性、有效交配频率、性别比和工蚁繁殖率。多位点 DNA 指纹技术可以精确测定原始社会性蜜蜂 Augochlorella striata（Halictidae）的这些参数。 DNA指纹揭示了群体内遗传关系的前所未有的分辨率，检测到诸如种内巢寄生和二倍体雄性等因素，这些因素分别混淆了相关性和性别比的估计。参数估计（i）证实了蚁后与工蚁在性别比例方面发生冲突的最新证据，（ii）暗示了单倍二倍体在工蚁行为进化中的作用。
Demonstrating the importance of haplodiploidy in the evolution of eusociality among the Hymenoptera (bees, wasps, and ants) requires estimation of four parameters: relatedness between cooperating individuals, effective mating frequency, sex ratio, and rates of worker reproduction. Multilocus DNA fingerprinting techniques permitted the precise determination of these parameters for the primitively eusocial bee Augochlorella striata (Halictidae). DNA fingerprints revealed an unprecedented resolution of genetic relationships within colonies, detecting factors such as intraspecific nest parasitism and diploid males that confounded estimates of relatedness and sex ratio, respectively. Parameter estimates (i) corroborate recent evidence for queen-worker conflict over the sex ratio and (ii) implicate the role of haplodiploidy in the evolution of worker behavior.
