From: Clustering analysis for the evolutionary relationships of SARS-CoV-2 strains
The pedigree diagrams of the existing types of the SARS-CoV-2 virus strains obtained through three hierarchical clustering methods of Ward-Euclidean, Average-Euclidean and Ward-Jaccard, respectively. The representative samples are selected utilizing method (2) proposed in “Representative sample selection methods”.
