Fig. 2From: MtOrt: an empirical mitochondrial amino acid substitution model for evolutionary studies of Orthoptera insectsThe ratio of exchangeability rates between mtOrt and mtMet/mtPan2013/mtInv models. The size of one circle represents the exchangeability rate between mtOrt and other models. The solid (unfilled) circles represent exchangeability rates where mtOrt is bigger (smaller) than the three models. For visualization, the large ratios are trimmed at 10 and marked with dotted circlesBack to article page
