Annotating Spike Protein Polymorphic Amino Acids of Variants of SARS-CoV-2, Including Omicron

Figure 1

Evolutionary relationships of variants of SARS-CoV-2. The evolutionary history was inferred using the neighbor-joining method [13]. The evolutionary distances were computed using the Kimura 2-parameter method [14]. Evolutionary analyses were conducted in MEGA X [12]. The tree was rooted to Wuhan-Hu-1.
