Evolutionary genetics: changed sex determination in honeybees.
In several insects and fish, and probably some mammals, the gene controlling the male-female switch has changed during evolution. It now seems that this has also happened in honeybees, where the sex-determining gene has now been shown to be a duplicate of another Hymenopteran sex-determining gene.
