Branches are colored according to the geographic origin of each sequence, as indicated in the legend (top left). Colored boxes highlight the position of the ten major Guatemalan HIV-1 subtype B clades (BGU-I to BGU-X). The number of sequences and the aLRT support values for each clade are indicated at the bottom. The tree was rooted using HIV-1 subtype D reference sequences. Branch lengths are drawn to scale with the bar at the bottom indicating nucleotide substitutions per site.</p
