θw, Watterson's nucleotide diversity estimator (1975) based on silent site; π, Nei's nucleotide diversity (1987) based on silent site; D, Tajima's D statistics (1989) based on the differences between the number of segregating sites and the average number of nucleotide differences; D* and F*, the neutral test proposed by Fu and Li (1993); and Hn, normalized Fay and Wu's H test statistics. Statistical significance: **P < 0.02 and *P < 0.05.
