^a First letter indicates expression in D. ananassae, second letter expression in D. melanogaster (M = male-biased, F = female-biased, U = unbiased). The last three rows show all male-, female-, and unbiased genes according to the classification in D. ananassae.
^b The total number of synonymous fixed differences.
^c The total number of nonsynonymous fixed differences.
^d The total number of synonymous polymorphisms.
^e The total number of nonsynonymous polymorphisms.
^f P-value was determined by G-test when applicable, otherwise by Fisher's exact test.
