Figure 3.
Expression turnover of sex-biased genes in the brain. (A) The fraction of sex-biased genes that are sex-biased in one, two, or three species. Also shown is the fraction of sex-biased genes that have “switched” sex bias between species (i.e., genes that are male-biased in at least one species and female-biased in at least one other species). (B) The fraction of genes in each species number class (one, two, three, or switched) that are located on the X Chromosome. For any given gene, the chromosomal location was taken to be the location of the D. melanogaster ortholog.
