The Fitch–Margoliash method uses a weighted least squares method for clustering based on genetic distance. Closely related sequences are given more weight in the tree construction process to correct for the increased inaccuracy in measuring distances between distantly related sequences. See more Distance matrices are used in phylogeny as non-parametric distance methods and were originally applied to phenetic data using a matrix of pairwise distances. These distances are then reconciled to produce a tree (a See more Distance-matrix methods of phylogenetic analysis explicitly rely on a measure of "genetic distance" between the sequences being classified, and therefore they require an MSA (multiple … See more • List of phylogenetics software See more Web30 人 赞同了该文章. 转载于： 系统发育树构建算法和软件 - xiaojikuaipao - 博客园 ，并根据自己的理解进行了修改和更正。. 构建系统发育树的方法包括：基于距离方法（e.g. …
