Figure 3. Whole genome and ORF 1a/b phylogenetic analysis of
Peruvian PDCoV strain reveals its evolutionary origin from a North
American PDCoV strain
For both whole genome and ORF 1a/b, the evolutionary history was
inferred by using the Maximum Likelihood method and General Time
Reversible model. The percentage of trees in which the associated taxa
clustered together is shown next to the branches. A discrete Gamma
distribution was used to model evolutionary rate differences among
sites. The tree is drawn to scale, with branch lengths measured in the
number of substitutions per site. This analysis involved 24 nucleotide
sequences. Evolutionary analyses were conducted in MEGA X.
