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. WebFigure 2. All the organisms within a clade stem from a single point on the tree. A clade may contain multiple groups, as in the case of animals, fungi and plants, or a single group, as in the case of flagellates. Groups that diverge at a different branch point, or that do not include all groups in a single branch point, are not considered clades.
