Inference of ancestral sex-biased expression state of genes differing in expression between D. melanogaster (Dmel) and D. ananassae (Dana), using D. pseudoobscura (Dpse) as the outgroup. For 47 genes showing conflicting sex-biased classifications between D. melanogaster and D. ananassae, we inferred the ancestral expression state using microarray data from D. pseudoobscura.
