The phylogenetic tree of gag 4 and gag 5 is indicated by red dots. Next to the branches is the proportion of trees in which the related taxa clustered together. The initial tree(s) for the heuristic search were automatically generated by applying the Neighbor-Join and BioNJ algorithms to a matrix of pairwise distances computed using the Tamura-Nei model and then picking the topology with the highest log-likelihood value. The branch lengths are measured in the number of substitutions per site, and the tree is depicted to scale. Each descending clade’s proportion of sites with at least one unambiguous base in at least one sequence is shown next to each internal node in the tree.
