  1. A, C, G, T, GCskew and ATskew refer to whole mitogenome content analysis. GC1, GC2, GC3 and Coding GC refer to the analysis of the mitochondrial coding-genes located in the H strand. See Additional file 4 for discriminated base composition values at first, second and third codon position of these 12 coding-genes located in the H strand
