Chromosomal enrichment analysis shows sex-specific differences. Bar chart represents the chromosomal distribution of differentially expressed genes in the male vs. female data. Light bars represent the significant genes on each chromosome; the number of genes assayed on each chromosome is represented by the total height of each bar. Chromosomes that passed the test for enrichment by Fisher's exact test (P < 0.05) are symbolized as †, ‡, § for male vs. female, male biased and female biased gene subsets, respectively.
