**neighbor**-

**joining method**: a new

**method**for reconstructing phylogenetic trees. The principle of this

**method**is to find pairs of operational taxonomic units (OTUs [= neighbors]) that minimize the total branch length at each stage of clustering of OTUs starting with a starlike tree.

Besides, what is the neighbor joining method?

The ** Neighbor ** - ** Joining Method ** . The ** neighbor ** - ** joining method ** is a special case of the star decomposition ** method ** . In contrast to cluster analysis ** neighbor ** - ** joining ** keeps track of nodes on a tree rather than taxa or clusters of taxa. The raw data are provided as a distance matrix and the initial tree is a star tree.

Also Know, what is maximum parsimony method? ** Maximum parsimony ** predicts the evolutionary tree or trees that minimize the number of steps required to generate the observed variation in the sequences from common ancestral sequences. For this reason, the ** method ** is also sometimes referred to as the minimum evolution ** method **.

Then, what is neighbor joining tree?

From Wikipedia, the free encyclopedia. In bioinformatics, ** neighbor joining ** is a bottom-up (agglomerative) clustering ** method ** for the creation of phylogenetic ** trees ** , created by Naruya Saitou and Masatoshi Nei in 1987.

What is Upgma tree?

** UPGMA ** (unweighted pair group method with arithmetic mean) is a simple agglomerative (bottom-up) hierarchical clustering method. The method is generally attributed to Sokal and Michener. The ** UPGMA ** method is similar to its weighted variant, the WPGMA method.
