p_AA,p_NT,p_S, and p_N, represent average number of amino acid, nucleotide, synonymous and non-synonymous nucleotide differences per site when calculated using the entire protein/nucleotide coding sequence along with the Z-test of selection. SE indicates standard error based on 1000 bootstrap replicates.
^aaverage transition/transversion ratio.
^bH₁: p_N<p_S and H_o: p_{N =}p_S.
