Your Maternal Story, Redefined.

Break through maternal line brick walls and follow your ancestral connections through history on the new mtDNA Tree of Humankind

A test for both biological males and females, mtDNA is used to help answer questions about relatedness on the direct maternal line.

WHO CAN USE MTDNA TESTING?

mtDNA is passed down from mother to all children

While both males and females inherit mtDNA, only biological females can continue to pass on mtDNA. mtDNA testing can help you discover and verify your direct maternal ancestry by connecting you with other individuals who are descendants of a shared common matrilineal ancestor.

CONNECT WITH YOUR mtDNA RELATIVES

Join the Worldā€™s Largest mtDNA Database

Trace your matrilineal ancestry and connect with relatives who share a common maternal ancestor. Whether itā€™s a grandmother from recent generations or an ancestor from centuries ago, our mtDNA test helps you uncover and understand your maternal heritage.

Follow the path of your direct matrilineal ancestors

Use mtDNA to determine where your direct maternal lineā€™s ancestors came from, their locations in historic times, and how they migrated throughout the world.

Here are the most frequently asked questions about FamilyTreeDNA. If you have additional questions, feel free to visit ourĀ Help CenterĀ or reach out to ourĀ Customer ServiceĀ team.

mtDNA refers to mitochondrial DNA which is passed from mother to child. While men receive mitochondrial DNA from their mother, they do not pass it on to their children. Testing mtDNA allows for investigation into your maternal line and can help identify living relatives whose mtDNA is similar to yours, as well as ancient migration routes your maternal ancestors may have taken.

Every individual who takes one of our mtDNA tests will also receive their mtDNA haplogroup. When humans left Africa tens of thousands of years ago, they departed in small groups that migrated into different parts of the world. Over many generations, each group developed distinct mutations allowing us to identify one from the other. We call these groups of mutations haplogroups, and they can tell us which migratory routes our maternal ancestors traveled.

If you have questions about any of your results, you can either contact one of our Customer Support Representatives or look through our mtDNA pages in our Help Center to learn all about mtDNA testing!

Your closest matches are your exact matches at the Full Sequence level. To determine which of those matches share a common ancestor with you more recently than the others, we offer several tools to help you compare your common genealogical and geographical connections, such as matrilineal Earliest Known Ancestors and locations and shared Family Trees. You can add your own genealogical information to your account (SurnamesĀ andĀ Earliest Know Ancestor), increasing the chance that a match may recognize their connection to you and reach out.

Your mtDNA results will provide you with a migration map that shows you the path your ancient matrilineal ancestors took out of or across Africa tens of thousands of years ago. You can also learn more about your recent matrilineal ancestry from connecting with your matches and utilizing tools that come with the results to learn more about where your matchesā€™ maternal Earliest Known Ancestors are from. Because you will share a common ancestor with your matches, you will also share a common geographic location with them. The tools included with the results and connections you make with your matches can help you determine where that location might be and who that common ancestor was.

The Mutations page breaks down your raw sequence for your mtDNA test results. Your mutations determine your matrilineal genetic signature, meaning both the ancient migration path that your direct maternal ancestors took and who your closest matrilineal matches are.Ā 

We compare your DNA to two reference sequences, the Reconstructed Sapiens Reference Sequence (RSRS) and the Revised Cambridge Reference Sequence (rCRS).

For the RSRS, each mutation will be grouped by region of the mitochondria, and then listed with the nucleotide base (A, T, G, C) read in the DNA of the reference found at the position, followed by the position, and then the nucleotide base (A, T, G, C) read in your DNA. For example, C16222T means that at position 16222, the reference sequence has a C and your DNA has a T.

For the rCRS, you will see another section that lists all of your mutations in a chart, broken down by each region of the mitochondria. The column headers in the rCRS mutations chart provide the following information:

  • Position: The location of the mutation

  • CRS: The nucleotide base (A, T, G, C) read in the DNA of the Cambridge Reference Sequence

  • Your Result: The nucleotide base (A, T, G, C) read in your DNA at this position. Blank means your DNA matches the Cambridge Reference Sequence.

Some mutations will be defined by a letter other than A, T, G, or C. These are mutations in progress, and they are referred to as heteroplasmies.Ā Learn more

Most mtDNA matches will be distant relatives, potentially sharing an ancestor hundreds of years ago. However, if your match has a genetic distance of 0, you may have a more recent common maternal ancestor.

Combining mtDNA with autosomal DNA (Family Finder) gives you a more comprehensive view of your ancestry. For recent genealogy, we recommend using a combination of Family Finder, mtDNA, and even Y-DNA to confirm maternal-line relationships while also connecting with relatives across all branches of your family tree.
