Distance Matrix
Methods
Convert sequence data into a set of
discrete pairwise distance values, arranged
into a matrix.
•Distance methods fit a tree to this
matrix.
•The phylogenetic
topology tree is constructed by using a cluster analysis
method (like UPGMA or NJ methods).
•The phylogeny
makes an estimation of the distance for each pair as the sum of branch
lengths in the path from one sequence to another through the tree.
