Estimates of mean substitution rates (×10⁻³ nucleotide substitutions per site per year), TMRCAs (in year) and the dN/dS for genotypes 1G, 2B and for the pooled dataset.

Best-fit models with the highest marginal log likelihood score for respective data sets are in bold. n: Number of sequences; SP:Structural protein; NSP:Nonstructural protein; HPD: Highest Posterior Density; TMRCA: Time to the Most Recent Common Ancestor; CoV: Coefficinet of Variation; NA: Not Applicable; dN: Nonsynonymous substitution; dS: Synonymous substitution. Estimates of mean substitution rates (×10−3 nucleotide substitutions per site per year), TMRCAs (in year) and the dN/dS for genotypes 1G, 2B and for the pooled dataset.
