The tree was generated by the maximum-likelihood method. Numbers at the branch nodes connected with subtypes indicate bootstrap values. The distinct HIV-2 subtypes are delineated. The scale bar indicates an evolutionary distance of 0.10 nucleotides per position in the sequence.
Vertical distances are for clarity only.
Back to article Figure 2. Numbers at the branch nodes connected with subtypes indicate bootstrap values. Arrows indicate Lebanese samples that clustered in different lineages depending on which parts of their genome were analyzed. The scale bar indicates an evolutionary distance of 0.10 nucleotides per position in the sequence. Vertical distances are for clarity only.
