Fig. 4: Analysis of amino acid substitutions in variants circulating in Ghana.
From: Genetic diversity of SARS-CoV-2 infections in Ghana from 2020-2021
a Frequencies of amino acid substitutions across all the SARS-CoV-2 proteins in all genomes that were sequenced. The mutations are sorted and coloured per gene. b Spike glycoprotein amino acid substitutions present/absent in major SARS-CoV-2 variants circulating in Ghana. Purple shading indicates substitutions within the lineages, whereas white indicates the absence of the substitution in a particular variant in all the samples. The bottom panel plot shows the frequencies of individual substitutions across all the samples.
