Sample Data
| Front | mtDNA |
| Back | DNA located in mitochondria, inherited from the mother (maternallyinherited) and can be used to trace maternal lineage far back in time. More info: It has slow mutation rates, making it useful for studying evolutionary relationships. Biologists can compare mtDNA sequences among different species to build an evolutionary tree. This is how they all maternal lineages can be traced back to one induvial woman that lived 200,000 years ago (Mitochondrial Eve). |
