How to interpret neighbour joining tree

WebI used 3 different but closely related protein groups, and done Phylogenetic tree analysis by using 2 method i.e. neighbor-joining and maximum-likelihood method with 1000 replicates using MEGA6. In both the tree obtained, in one tree (neighbor-joining) it is showing protein group 1 is similar to protein group 2, in other tree (maximum-likelihood) … WebThere are two general categories of methods for constructing phylogenetic trees: clustering methods and tree searching methods. The clustering methods are known as the distance-matrix method, in which the UPGMA and neighbor-joining methods are generally used.
