(a) Overlap of organ-specific genes with positively and negatively selected genes (dN/dS > 1 and dN/dS < 0.1, respectively). The numbers in the middle represent organ specific genes that were found to be neither positively or negatively selected. Sums deviate from the numbers shown in Fig. 2c as only genes were counted that could be examined in both analyses (gene expression and selection). A “*” represents a significant overlap (Fisher test, p = 0.002 for brain-specific and negatively selected genes). (b) Biological processes found to be significantly enriched in the intersection of brain-specific expressed and negatively selected genes.
