4. Phylogenetic networks of 58 haplotypes of SARS-CoV-2 with the outgroup bat-RaTG13-CoV using the whole coding region matrix (A) and 120 substitution sites (B), referring to all variable sites of coding regions in SARS-CoV-2 haplotypes.
The bottom scale bars represent the number of substitutions per site. The open box on branches of bat-RaTG13-CoV (A), H15 (A, B), and H17 (A, B) indicating a long branch was clipped.
