Introgressed cis-regulatory divergence generates greater sexual dimorphism in expression than introgressed trans-regulatory factors. (White boxes) The distribution of the absolute differences between males and females in the effects of introgressed factors measured by microarray, as well as the absolute difference between the sexes in allelic expression measured by pyrosequencing. (Gray boxes) The distribution of the absolute differences in expression between males and females resulting from whole-genome divergence between the parental simB and mau12 strains for the same genes.
