Figure 2: Evolutionary tree involved 34 whole genome nucleotide sequences of SARS-CoV-2 (~29.9 kbp). Nine clinical samples (bulleted in blue circle), one cell culture isolate [EPI ISL 2501532,2020-05-19] (bulleted in blue diamond), Covaxin/BBV152 vaccine strain (bulleted in green diamond), SARS-CoV-2 reference strain (bulleted in red square), and other nearest SARS-CoV-2 whole genome sequences. The tree was rooted to the ancestral clade S. The evolutionary history was inferred by using the Maximum Likelihood method and General Time Reversible (GTR +G+i) model conducted based on best fit model in MEGA X
