Fig. 7From: Pango lineage designation and assignment using SARS-CoV-2 spike gene nucleotide sequencesDistribution of the number of Pango lineages in each lineage set, using a mutation frequency threshold of X = 95%. Three hundred thirty-seven sets contain only a single lineage and so are uniquely distinguishable by their consensus spike haplotype. Twenty-eight sets contain two Pango lineages, and so onBack to article page
