Figure 4From: Phylogenetic analysis consistent with a clinical history of sexual transmission of HIV-1 from a single donor reveals transmission of highly distinct variantsRelaxed-clock tree for env. Between-host divergence, in terms of pre-transmission evolution, was quantified as the estimated tMRCA using a Bayesian MCMC based approach. Env C2V5 fragment sequences from P1 and P2, sampled at day 63 by SGA, were calibrated against within-host divergence since the estimated time since transmission as well as the mean rate of substitution from the reference dataset.Back to article page
