^{a} The probability of rejecting the null hypothesis of strictneutrality (d_{N} = d_{S}) in favor of the alternative hypothesis (d_{N} > d_{S}). Values of P less than 0.05 are considered significant at the 5 % level

^{b} The test statistic (d_{N}  d_{S}) is shown. d_{S} and d_{N} are the numbers of synonymous and nonsynonymous substitutions per site, respectively. The variance of the difference was computed using the bootstrap method (1000 replicates)
