We contrasted brood and honey production in colonies where we diluted worker relatedness with those elements of productivity in colonies where relatedness was unmanipulated. Relatedness manipulation did not affect overall brood production, worker or drone brood production, the worker to drone brood sex ratio, or the volume of honey produced. Thus, there is no evidence that honey bees discriminate close from distant relatives or, more importantly, that dilution of the coefficient of relatedness within a colony has any impact on the efficiency of that colony. 收起
