Unweighted tree

WebApr 11, 2024 · Phylogenetic tree construction is a complex process that involves several steps: 1. Selection of molecular marker. The first step in constructing a phylogenetic tree is to choose the appropriate molecular marker. The choice of molecular marker depends on the characteristics of the sequences and the purpose of the study. UPGMA (unweighted pair group method with arithmetic mean) is a simple agglomerative (bottom-up) hierarchical clustering method. It also has a weighted variant, WPGMA, and they are generally attributed to Sokal and Michener. Note that the unweighted term indicates that all distances contribute equally to each average that is computed and does not refer to the math by which it is achieved. Thus the simple averaging i…
