Participation in DNA Relatives

DNA Relatives is one of the most interactive features of 23andMe, allowing you to find and connect with genetic relatives and learn more about your family.

This feature finds matches by comparing your DNA with that of other 23andMe members who are participating in DNA Relatives. When two people share identical segments of DNA, this indicates that they share a recent common ancestor. The length and number of these identical segments is used to predict the relationship between relatives. Connecting with these relatives - even distant cousins - can help uncover information about your family history.

When your results are available, you have the option to opt in to participate in the DNA Relatives feature. You'll see the following notice when you log in to your account:

If you are anticipating seeing a known relative in your list and that relative does not appear, check with them to make sure they have opted in to participate in DNA Relatives.
