Using mtDNA sequencing results, any two individuals can compare their profiles to see whether they descended from the same maternal line. If the mtDNA test shows that two individuals have different mtDNA profiles, it would conclusively prove that they did not descend from the same maternal lineage. You can use your mtDNA profile to compare with other individuals in your tree to confirm a positive linkage, verify new linkages, or verify findings from your paper research. You can also use your mtDNA markers to search our global database to find potential matches from around the world.
