Figure 3.

The ratio of p-distance (p-dist) of the promoter regions versus predicted nucleotide mutation rate [calculated as dS (proportion of synonymous substitutions per synonymous site in the exons)] in pairwise comparisons for each PAG gene represented in the genome build. A. Comparisons with the proximal 1000 bp of the promoter region. B. Comparisons with the proximal 500 bp of the promoter region. The p-distance of the promoters was shown on the Y-axis and the dS of their protein coding regions were displayed on the X-axis. The unique marks of a particular color and shape in the figure represent the pairwise comparisons of boPAG against each of the other PAGs included in the analysis. The listing of PAG genes and their indicators are shown in the legend.
