Extended Data Fig. 2 | Phylogenetic trees based on the complete S and RdRp
gene sequences of coronaviruses. a, b, Phylogenetic trees on the basis of the
gene sequences of S (a) and RdRp (b) are shown. 2019-nCoV and bat CoV RaTG13
are shown in bold and in red. The trees were constructed using the maximum
likelihood method using the GTR + G substitution model with bootstrap values
determined by 1,000 replicates. Bootstraps values of more than 50% are
shown.
