Figure 4.
The histogram shows the average GC3 increment in the three functional categories comparing human vs frog (H/F) and human vs lizard (H/L). Color code of histogram bars is as in Figure 1. In the H/F comparison the standard error for the Blue, Black and Red bars were, respectively, 5.1 × 10-3, 3.7 × 10-3 and 5.5 × 10-3. In the H/L comparison the standard error for the Blue, Black and Red bars were, respectively, 3.8 × 10-3, 2.8 × 10-3 and 3.9 × 10-3.
