Some species of wasps are socially polymorphic, which means they can be either solitary and produce offspring by themselves, or they can live socially, with the first daughter remaining in the nest as a worker wasp to help rear her sisters. Solitary wasps produce an average of 10 female offspring in their lifetimes. What is the minimum number of female offspring a social worker wasp should help raise for altruism to be favored by kin selection? [Hint: just like bees, wasps are haplodiploid, use rB > C .] 10 12 14 16.
