Is haplodiploidy a necessary condition for the evolution of eusociality?

Question

Quizplus · Accepted Answer

While haplodiploidy is often associated with eusociality, it is not a necessary condition for its evolution. True eusociality is found in organisms that do not have a haplodiploid genetic system, such as termites and naked mole rats. Therefore, option C is the correct choice. Option A is false because while true eusociality is found mainly in the Hymenoptera, this does not necessarily mean haplodiploidy is a necessary condition. Option B is incorrect because while haplodiploidy can increase the relatedness between sisters, it is not the only way to achieve high indirect fitness. Lastly, option D is incorrect because while some organisms can have multiple fathers, this does not mean that coefficients of relatedness between sisters are never 0.75.
