Ka/Ks distributions for PRs and for retropseudogenes ( RψG s). (A) Distribution of Ka/Ks for human PRs (n = 262) meeting the local gene order test (N homologs ≤ 1), compared to Ka/Ks for the RψG s (n = 183). All sequences were required to have protein sequence identity ≥ 60.0% with their parent sequences. (B) As in (A), but for mouse PRs (n = 318) and RψG s (n = 220).
