Fig. 3From: Complete mitochondrial genomes reveal robust phylogenetic signals and evidence of positive selection in horseshoe batsCorrelation analyses. The 13 mitochondrial protein-coding genes of the bat species with low echolocation frequency relative to body size are indicated by dots. The lines are the best-fitted line. A Correlation between total number of mutations and gene length. B Correlation between synonymous mutations and gene length. C Correlation between non-synonymous and synonymous mutations. The correlation coefficient r and P value are shown in the lower right corner for linear regression.Back to article page
