Population analysis in HIV subtypes. A total of 15,453 HIV sequences were obtained from the Los Alamos HIV database, and amino acid (aa) sequences were compared to that in the corresponding HXB2 codon sequence. Population (%) of IN:M50I (a), RH:N79S (b), IN:S17N(c), and the frequency of the combination of RH:N79S with IN:M50I (d) and IN:S17N with IN:M50I (e) in each subtype is depicted using pie charts.
