Phylogenetic tree of 17 Gag isolates (A) and 13 pol isolates (B), generated via Neighbor Joining method. The distances were computed using the Kimura 2- parameter model. Evolutionary analysis were conducted in MEGA X. Sum of branch optimum length = 0.66910448. 1000 bootstrap test replicates are shown near to scale with branch lengths as those of the evolutionary distances used to infer the phylogenetic tree.
