Fig 7. SARS-CoV-2 genome variants for China, East Asia, Hong Kong, and Taiwan.

The outer track shows the gene/protein coding regions displayed in blue. The four inner tracks display nucleotide frequencies (green (A), orange (C), blue (G), and red (T)) at 44 locations with an alternate allele frequency > 1%. The inner-most track of arcs shows variant locations having a high linkage with r² values ranging from 0.8 (narrow, light) to 1 (wide, dark). Abbreviations: leader protein (LP), 3C-like-proteinase (3C-P), RNA-dependent-RNA-polymerase (RNA-Poly), 3′-to-5′-exonuclease (3′-5′-Exo), 2′-O-ribose-methyltransferase (2′ORM).
