摘要

本文提出了一种新的DNA序列距离计算方法。给定一组物种，该方法首先将每个物种的DNA序列编码成特征向量，然后根据这些特征向量计算该物种集的距离矩阵。得到的距离矩阵可用于构建系统发育树进行系统发育分析。这种方法绕过了进行多序列比对的复杂性，避免了选择单个基因进行物种树构建的模糊性。

A new distance computing method for DNA sequences in phylogenetic analysis

In this paper we proposed a new distance computing method for DNA sequences. Given a set of species, the method first codes the DNA sequences of each species into a characteristic vector, and then computes a distance matrix for the set of species based on these characteristic vectors. The distance matrix obtained can be used to construct phylogenetic trees for phylogenetic analysis. Such a method bypasses the complexity of performing multiple sequence alignments and avoids the ambiguity of choosing individual genes for species tree construction.
