Figure 2From: Evaluation of the models handling heterotachy in phylogenetic inferenceBranch lengths for the two partitions in the case of the mitochondrial alignment of mammals (3591 sites, 17 species). The shape parameter of the Γ distribution was estimated to be 0.4. The weights are 0.40 for component I (B) and 0.60 for component II (A).Back to article page
