Evolution of X-linked and autosomal sex-biased genes. Percentages of male- (blue) and female-biased (pink) genes found to be unique when comparing the genomes of A. gambiae (An) with A. aegypti (Ae), C. quinquefasciatus (Cu) and D. melanogaster (Dm) are presented for X-linked (upper panels) and autosomal genes (lower panels). Statistically significant differences were evaluated by hypergeometric distribution using as reference the fraction of unique genes found in all X-linked or autosomal genes studied (P < 0.05, one asterisk; P < 0.01, two asterisks).
