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.
