Figure 2

Differences per site for homologous genes or groups of sites in the two Agkistrodon piscivorus genomes and in the two viperid genomes . The differences per site are shown for a comparison of Api1 and Api2 (A), and for A. piscivorus (mean of Api1 and Api2) and Ovophis okinavensis (B). Differences are shown only for the longer protein-coding genes. For the control regions only (shaded black), differences are shown for each aligned site including indels (e.g., CR1+I), or excluding indels (e.g., CR1-I). For all other genes, indels are not included in the difference measure. The bars for 3rd codon positions (3 rd Codon) and for all codon positions (All Codon) are summed over all protein-coding genes.
