Fig. 6From: Biogeographic history and high-elevation adaptations inferred from the mitochondrial genome of Glyptosternoid fishes (Sisoridae, Siluriformes) from the southeastern Tibetan PlateauDetection of positively selected codon sites in the complete mitochondrial protein genes (excluding ND6). The MrBayes tree topology (Fig. 2) was used for this analysis. “ωpss” represents the ω value of positively selected sites. “P-value (LRT)” represents the p-value of the likelihood ratio test of the alternative hypothesis (ωpss = MLE) and the null hypothesis (ωpss = 1). The branches in which positively selected codon sites were detected are indicated by bold black linesBack to article page
