Haplodiploidy is necessary for eusociality.
Answer the following statement true (T) or false (F)
False
Not necessarily. Termites and naked mole rats have complex societies, but do not have haplodiploidy. However, haplodiploidy does seem to favor the evolution of eusociality, because it increases the relatedness of female siblings (75%) compared to mothers and progeny (50%).
