This method gives essentially the same result as those obtained by Nei and Li's method bu saves a large amount of computer time.The variances of the quantities estimated can be obtained by the jackkife method, and these variances are very similar to those obtained by Nei and Jin's more sophisticated method. A similar method can also be applied to DNA sequence data. aDivergence aDivergencia aDiversidade de nucleotideos aNucleotid diversity aNucleotide substitutions aSubstituicoes de nucleotideos1 aMILLER, J.
