Figure 5

The nucleotide skew for each of the 13 mitochondrial protein-coding genes of Paratemnoides and Pseudogarypus. The genes are arranged in the order they are located in the mitochondrial genome, with the circular genome arbitrarily linearized at the 5' end of the ND2 gene. Boxes shaded orange and offset upwards depict genes encoded on the major strand, while boxes shaded yellow and offset downward depict genes encoded on the opposite strand. The green shaded box depicts the skew averaged across all 13 genes. For each gene, the average AT and CG skews at each codon position are shown. Blue depicts cytosine and adenine skew, red depicts guanine and thymine skew. An excess of cytosine is depicted as an upward blue bar, while an excess of guanine is depicted as a downward red bar. An excess of adenine is depicted as an upward blue bar, while an excess of thymine is depicted as a downward red bar.
