Set 3 of reference sequences — results obtained by using hierarchical clustering via dendrogram plots. Numbers at the beginning of each virus label indicate the cluster that virus is a member of as a result of the clustering algorithm. (A) when the cut-off $C$ is equal to 0.7 and using Set 3 of reference sequences only: there are 6 clusters where cluster “5” covers all examined viruses in the Sarbecovirus sub-genus. (B) when cut-off $C$ is still equal to 0.7 and the dataset now merges between reference sequences and 16 representative SARS-CoV-2 sequences (merged set). (C) using the merged set with $C=0.1$. (D) using the merged set with $C=0.03$. (E) using the merged set with $C=0.01$. (F) using the merged set with $C=0.001$.
