Summary of selection in the mitogenome of Phrynocephalus. The 13 mitochondrial coding genes are represented and labelled (figure does not include tRNAs). Filled black circles represent positively selected sites (p < 0.001) identified by TreeSAAP analysis. The dataset was analysed for significant changes in each of the 31 physicochemical properties. The y-axis represents the number of properties for which selection was inferred (for each site). Open triangles are positively selected sites identified by independent analyses of ω
