Figure 4From: Snake mitochondrial genomes: phylogenetic relationships and implications of extended taxon sampling for interpretations of mitogenomic evolutionML phylogram showing branch lengths for the topology in Fig. 2 estimated with rRNA nucleotide data. Analysis was run under the GTR+I+Γ model. Note that branch lengths are drawn to the same scale in Figs. 4, 5 and 6 to aid comparison.Back to article page
