Study Notes
Phylogenetic Tree Construction
- A phylogenetic tree is constructed from a distance matrix using clustering algorithms
- Clustering algorithms link the least distant pair of taxa first, followed by successively more distant taxa
Clustering Methods
-
UPGMA Clustering
- Unweighted Pair Group Method using Arithmetic averages
- Simplest method of phylogenetic tree construction
-
Neighbor Joining
- Tries to correct the UPGMA method's assumption of equal evolutionary rates among all taxa
