WebA phylogenetic analysis typically consists of five major steps. The first stage comprises sequence acquisition. The following step consists of performing a multiple sequence alignment, which is the fundamental basis of constructing a phylogenetic tree. The third stage includes different models of DNA and amino acid substitution. WebA phylogeny is a diagram that represents the hypothesized evolutionary relationships among species or higher taxa.
