Evolutionary relationships of taxa of HBV

The evolutionary history was inferred using the Neighbor-Joining method. The optimal tree with the sum of branch length = 0.83994352 is shown. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the Maximum Composite Likelihood method and are in the units of the number of base substitutions per site. The analysis involved 62 nucleotide sequences. All positions containing gaps and missing data were eliminated. There were a total of 3054 positions in the final dataset. Evolutionary analyses were conducted in MEGA7.
