In many social insects both workers and queens can lay male eggs. In a comparative study, Hammond and Keller (see article) show that, contrary to expectation, relatedness does not explain the proportion of worker-produced males. This suggests that regulation of worker reproduction occurs because selfish reproduction by workers reduces colony productivity.
