Relatedness may contribute to the evolution of sociality. Ants, Bees and Termites Consider the actual measures of relatedness in bees relative to the theoretical maximum of 0.75. This implies that a single queen mates multiply, and thus the sisters of a colony are really half sibs, or the queen shares her reproductive roles with other females in the colony. Thus, haplodiploidy does not invariably lead to high relatedness. Consider termites which form very similar colonies to ants in their extreme worker specializations.
Termites have warrior castes with spray nozzles similar to ants.
And there is a single bloated, egg-laying queen in the termite colony that produces all the eggs. Recall that such oedipal inbreeding can generate higher levels of relatedness, which can rival the 0.75 of hymenoptera. Similar sib-sib inbreeding can produce progeny with 0.75 relatedness. If inbreeding is not a problem then inbreeding can readily promote the evolution of eusociality. It turns out that naked mole rats have a high degree of relatedness within a colony, and great differentiation among colonies.
