*Male- and female-specific sets include genes that are expressed only in that sex, whereas sex-biased are expressed, on average, three-fold higher in one sex than the other. ^†X² and p-values derived from Kruskal Wallis; three asterisks denote p-value < 0.0001. ^‡Ms, male-specific; Mb, male-biased; Fs, female-specific; Fb, female-biased; U, unbiased. ^§F, female; M, male; U, unbiased; NSS, non-sex-specific; SS, sex-specific. ^¶Divergence refers to lineage specific divergence along the D. simulans branch.
