Figure 2.

Nucleotide and amino acid comparison of imported genomes to the reference severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Wuhan genome (NC_045512.2). Only single-nucleotide polymorphisms (SNPs) that differentiate the genomes from the reference are shown in the condensed SNP alignment. Sites identical to the reference are shown in grey, changes from the reference are indicated and colored by nucleotide (green for thymidine, red for adenosine, blue for cytosine, yellow for guanine, and black for gaps). If a mutation results in an amino acid change, the column label indicates the gene, reference amino acid, amino acid site, and amino acid change in brackets. The unrooted phylogeny (branch lengths number of mutations) on the right shows the relationships between depicted genomes and was rooted on the reference sequence.
