Figure 1. Phylogenetic Trees inferred using MrBayes.

Phylogenetic trees estimated from the mtDNA coding sequence data from eight species of Pacific salmon. The Bayesian analysis predicted three trees with posterior probabilities of (a) 0.595, (b) 0.343, and (c) 0.061. The foreground branch for the branch-site analysis is identified with a bold line. Trees were drawn without distances because Mr. Bayes estimates distances for only the most probable tree.
