Breeding And Selecting For Colonylevel Traits

Unlike all other livestock, the productivity of honey bee colonies does not depend primarily on individual physiological traits, like growth rate, but on social traits, like honey hoarding and defensiveness. Even a trait like disease resistance is strongly influenced by social factors (e.g. hygienic behaviour) (Evans et al., 2006), as well as by the individual's innate immune system. Thus, when beekeepers seek to genetically improve honey bee stocks they are primarily interested in improving...

Proboscis Extension Response Honey Bee

To understand honey bee behavioural genetics, we must first appreciate the genetic structure of colonies. A colony is neither an individual nor a FIG. 5 The social and genetic structure of a honey bee colony. A single queen mates with multiple fathering drones to produce female worker offspring. The offspring sired by each drone represent different patrilines among the workers. Behavioural variation among patrilines can indicate that behavioural variation has a genetic basis. The queen will...
