Lethality in hybrids between Drosophila melanogaster and its sibling species Drosophila simulans is caused in part by the interaction of the genes Hybrid male rescue (Hmr) and Lethal hybrid rescue (Lhr). Hmr and Lhr have diverged under positive selection in the hybridizing species. Here we test whether positive selection of Hmr is confined only to D. melanogaster and D. simulans. We find that Hmr has continued to diverge under recurrent positive selection between the sibling species D. simulans ...[more]
