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. WebOct 14, 2024 · A phylogenetic tree is a tree that shows the evolutionary relationships based on a common ancestor. Thus, when drawing a phylogenetic tree using the concept of maximum parsimony, the amount of parallel evolution is minimized. Therefore, maximum parsimony will generate the tree much quicker than other methods.
