From: Genetic variability in E6, E7 and L1 genes of Human Papillomavirus 62 and its prevalence in Mexico
Phylogenetic tree showing reference HPVs from alpha-3 species and 13 HPV62 Mexican sequences based on E6/E7 genes. The evolutionary history was inferred by using the Maximum Likelihood method based on the Tamura-Nei model [37]. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. The analysis involved 18 nucleotide sequences. Evolutionary analyses were conducted in MEGA7 [38]. The GenBank accession number of each HPV genotype reference from alpha-3 species is included in parentheses
