Fig. 4From: Applicability of several rooted phylogenetic network algorithms for representing the evolutionary history of SARS-CoV-2Two examples of phylogenetic networks constructed by the Tree-Child algorithm. a From the block-based tree set consisting of taxon selection A, after edge contraction (l = 0.01 and s = 90), followed by resolving multifurcations. b From the gene-based trees consisting of taxon selection B, after edge contraction (l = 0.01 and s = 90), followed by resolving multifurcations. Colours indicate the main clades, as described in the caption of Fig. 2. Taxon selections (A, B and C) are annotated between bracketsBack to article page
