Figure 2.

Overlap (blue region) between genes significantly differentially expressed between humans and chimpanzees and associated with nucleotide differences (green region) [31]or large insertion and deletion differences (red region) between the species. On average, fewer than 9% of genes differentially expressed at the life stages and tissues examined were associated with both types of variation. The number of differentially expressed genes associated with nucleotide differences as determined by Khaitovich et al. [31], as well as the number of differentially expressed genes associated with large insertions and deletions (INDELs) as determined in this study, are shown. The number of overlapping genes are shown at the intersection.
