| tRNAs | 158 | 5.9 | |
| 12S Ribosomal RNA | 99 | 3.7 | |
| 16S Ribosomal RNA | 125 | 4.7 | |
| NADH dehydrogenase subunits | 996 | 37.4 | |
| Cytochrome c oxidase subunits | 431 | 16.2 | |
| Cytochrome b | 217 | 8.1 | |
| ATP synthase subunits | 211 | 7.9 |
Loci positions were obtained from MitoMap (www.MitoMap.org). Percent calculations included poly-x sites (Table 1) as single events in nucleotide counts. Note: The overlap between several of these categories means that the number of variant sites will be higher than reported in the text and the percentages will sum to greater than unity.
