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.
