Abstract

A simple method is proposed for estimating the average number of nucleotide substitutions per site within and between populations for the case where a large number of individuals are examined for many restriction enzymes. This method gives essentially the same results as those obtained by Nei and Li's method but saves a large amount of computer time. The variances of the quantities estimated can be obtained by the jackknife 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.

摘要

本文提出了一种简单的方法,用于估计在对大量个体进行多种限制性内切酶检测的情况下,群体内部和群体之间每个位点的核苷酸替代平均数量。该方法得到的结果与内和李的方法基本相同,但节省了大量的计算机时间。估计量的方差可以通过刀切法获得,这些方差与内和金更复杂的方法得到的方差非常相似。类似的方法也可以应用于DNA序列数据。
