From: Analysis of 3.5 million SARS-CoV-2 sequences reveals unique mutational trends with consistent nucleotide and codon frequencies

Fig. 6

Nonsynonymous Mutations are Greatly Preferred in SARS-CoV-2 Omicron and Delta when Compared to Other Viruses. Both axes represent individual codons, with each point on the heatmap representing a mutation from one codon to the other. Darker points on the heatmap represent more frequent mutations. Mutations within the black boxes are synonymous, and mutations outside these boxes are nonsynonymous. Individual panels show heatmaps for A 1,407,663 SARS-CoV-2 Delta Spike Protein sequences ranging from 10/2020 to 06/2022, B 1,195,200 SARS-CoV-2 Omicron Spike protein sequences ranging from 11/2021 to 07/2022, C 15,080 H1N1 HA protein sequences ranging from 01/1989 to 02/2019, D 29,045 H3N2 HA sequences ranging from 12/1980 to 06/2022, E 531 MERS-CoV Spike Protein Sequences ranging from 12/2008 to 04/2019, and F 1676 Dengue 1 E Protein Sequences ranging from 01/2005 to 10/2019
