Bayesian consensus tree over time of HIV-1B polymerase gene in the DR. A Bayesian consensus tree was selected by TreeAnnotator software employing a Bayesian Skyline Plot (BSP) model. The data set included 195 HIV-1 subtype B sequences from the DR. The Markov chain Monte Carlo (MCMC) chains run 200×106, with a sample every 1,000 generations. The colors indicate the year of the sample, and bullets (●) indicate the branches with a posterior probability value above 90%.
