Fig. 1.

Schematic presentation of parts of the SARS-CoV-2 genome that were PCR amplified and sequenced. The span of each of the amplicons 1–5 is shown. V1–V11 that are the positions of various informative sequence variations and the positions of six other variations that were genotyped are indicated with filled circles. The virus strains that associate with the sequence variations are also designated. V3 (22992G>A) is not shown because it is observed on both the H1a and H1b backgrounds (see text). The genes of the virus genome are shown, and the names of several of the encoded proteins are written in parentheses.
