Sliding window analysis of complete mt genome sequences of Hypodontus macropi from different hosts. The three operational taxonomic units (OTUs) of H. macropi were from Macropus robustus robustus (OTU-C), Macropus bicolor (OTU-G) and Thylogale billardierii (OTU-J). The black line indicates nucleotide diversity comparing all the three OTUs; whereas three other symbols (a square, a circle and a plus sign) indicate pairwise comparisons across the mt genomes of OTU-C, OTU-G and OTU-J. Nucleotide diversity, measured iteratively every 10 bp over 300 bp windows of aligned mtDNA sequence data indicate peaks and troughs of sequence variability. Linearized maps of mtDNA are provided for each aligned data set, with the highest peaks of variability falling within the non-coding AT-rich regions.
