Comparison of sequences SAO21, SAO22 and the characteristic mutations for lineage B.1.351. Columns correspond to positions along the genome; uninformative sites (with all 0’s or 1’s) and those with singleton mutations (with exactly one 1) are not shown. Light blue: ancestral state, dark blue: mutated state, white: missing data. Red crosses highlight sites of recurrent mutations identified by KwARG. Sites bearing the characteristic (nonsynonymous) mutations of lineage B.1.351 (Tegally et al. 2021) are highlighted in orange.
