Figure 4From: Identification and characterization of insect-specific proteins by genome data analysisKa/Ks distribution. Nonsynonymous and synonymous substitution rates (Ka and Ks) were estimated for Drosophila specific, insect-specific, and eukaryote/opisthokont core proteins. Drosophila specific proteins are shown in black, insect-specific proteins in red and eukaryote/opisthokont core proteins in green. (a) Cumulative percentage of Ka/Ks ratios; (b) Ka/Ks versus Ks ratios.Back to article page
