Fig. 5From: Rooting phylogenetic trees under the coalescent model using site pattern probabilitiesApplication of the rooting method to the rattlesnake data set. a The 8-taxon species tree rooted by outgroups: A. contortrix and A. piscivorus. The inferred root position is labeled by a red line. b The unrooted 8-taxon species tree, with each branch labeled from ①to ⑬. The root position indicated by our method is labeled in red. c The unrooted 6-taxon species tree (with outgroups removed), with each branch labeled as in b. The rooting position indicated by our method is labeled in redBack to article page
