From: Pango lineage designation and assignment using SARS-CoV-2 spike gene nucleotide sequences
Genetic diversity in the spike protein of SARS-CoV-2 sequences for each of the Pango lineages that correspond to the four main variants of concern. Each coloured dot shows the genomic position of a non-synonymous (green), synonymous (beige), or indel (orange) mutation. The vertical axis shows the number of designated sequences that exhibit non-synonymous variation at each amino acid position (log10-scaled). In each plot, mutations were defined by comparing sequences with a common reference strain, Wuhan/WH04/2020 (EPI_ISL_406801). A Lineage B.1.1.7 (alpha). B Lineage B.1.351 (beta). C Lineage P.1 (gamma). D Lineage B.1.617.2 (delta)
