Histogram of sex dependent expression changes (intensities as arbitrary units) obtained for digestive gland of M. edulis upon 21d exposure to 0.5 mg/L crude oil (oil) and 0.5 mg/L crude oil spiked with a mixture of APs and PAHs (0.1 mg/L; sO); CF = control females, CM = control males, sOF = spiked oil females, sOM = spiked oil males, oilF = oil females, oilM = oil females; males are in blue and females in orange; the upper five represent female-specific and lower three male-specific peaks. Significantly different at 0.05 ≥ p ≥ 0.01, **, at 0.01 ≥ p ≥ 0.001, ***, at p < 0.001.
