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

Figure 5

(a) Selection site analysis of SARS-CoV2 genomes under the influence of purifying selection (upper panel) and corresponding alignment at the particular codon position under high purifying selection bias (indicated by ) is shown in the lower panel. (b) Selection site analysis of SARS-CoV2 genomes under the positive selection bias (upper panel) and the corresponding alignment at the particular codon position (indicated by ) under high positive selection bias is shown in the lower panel.
