Maximum-likelihood phylogenies. Unrooted maximum likelihood phylogenetic trees from (a) complete HCV genome, (b) polyprotein, (c) 5' UTR, and (d) the Okamoto region of NS5B. Taxon labels indicate HCV genotype and subtype from Table 1. Due to our focus on the consistency of subtype classification and the relative branching topology among subtypes, each tree is scaled independently.
