Figure 4From: Support for the reproductive ground plan hypothesis of social evolution and major QTL for ovary traits of Africanized worker honey bees (Apis melliferaL.)An additional significant QTL for ovary size was identified in the ABC5 backcross population. This QTL is identical to the behavioral pln1 QTL, demonstrating pleiotropy as predicted by the reproductive ground plan hypothesis of social evolution in honey bees.Back to article page
