Fig. 6From: Pango lineage designation and assignment using SARS-CoV-2 spike gene nucleotide sequencesNumber of distinct spike nucleotide sequences (SNS) in designated Pango lineages with complete spike sequences. Some of the very large lineages, for instance B.1.1.7 (count = 3893), B.1.177 (count = 2974), and B.1 (count = 2763) have many SNS, whereas the majority of lineages have fewBack to article page
