From: A new perspective on phylogeny and evolution of tetraodontiform fishes (Pisces: Acanthopterygii) based on whole mitochondrial genome sequences: Basal ecological diversification?

Figure 2

Patterns of sequence variation in the mitochondrial genomes of 25 tetraodontiforms and two outgroups. Pairwise transitional (TS) and transversional (TV) substitutions per site were plotted against evolutionary distance as a substitute for absolute geological time. Gamma-corrected maximum likelihood distances using the mtREV + F model [75] and derived from deduced amino acid sequences for the 13 protein-coding genes were used for evolutionary distances.
