Phylogenomics Analysis of SARS-CoV2 Genomes Reveals Distinct Selection Pressure on Different Viral Strains

Figure 2

(a) Evolutionary divergence of 82 genomes is shown. Divergence is shown in terms of the number of base substitutions per site between a pair of genomes. (b) Homogeneity in the substitution patterns between the 82 genomes is shown. The probability of rejecting the null hypothesis, i.e., sequences evolved with the same pattern of substitution, is represented.
