D, nucleotide diversity: average number of nucleotide substitutions per site between pairs of sequences. Standard errors are indicated in parentheses. dN, average number of nonsynonymous substitutions per nonsynonymous site. dS, average of synonymous substitutions per synonymous site. dN/dS, average of the ratio between nonsynonymous and synonymous substitutions for each pair of comparisons. dN, dS, and dN/dS were estimated by the PBL method (21, 33).
