Figure 6.

Scatter plots showing Ka/Ks ratio comparisons between TPA sequences and their respective orthologous parental protein coding genes for: (a) human/dog comparisons, (b) human/mouse comparisons. Ka/Ks values for TPAs, that are significantly less than values for neutral selection determined by simulation, are indicated as circle symbols, else the Ka/Ks values are indicated with square symbols. Those TPAs that have a disrupted protein domain of known three-dimensional structure are indicated with unfilled symbols, those without such a domain are indicated with filled symbols.
