Figure 2From: A new perspective on phylogeny and evolution of tetraodontiform fishes (Pisces: Acanthopterygii) based on whole mitochondrial genome sequences: Basal ecological diversification?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.Back to article page
