Relative Finder Information (v0.3):

Relative finder allows you to search for biological relatives based on DNA matches. If you decide to get a report, you will be able to see the names, contact information, estimated relationship, and the location of shared DNA segments for each potential relative. Your relatives will be able to see the same information about you. The tool is currently experimental and under development.

This is how a basic relative finding report looks:

Interpreting your relative finder report:

"High Certainty Matches" refers to users who share many long segments which likely originated from a recent common ancestor. "Speculative Matches" refers to users who share long segments, but more likely due to multiple distant ancestors rather then a single recent one.

Things to consider
Relative finder reports allow you to learn more about your family and genealogy. However, in some cases, it can reveal unexpected findings such as non-paternity events. The report also presents the DNA segments that you and your relative share and classifies the shared segments as ancient and recent segments using a statistical algorithm (right most column). With this information, you and your relative can better understand how you are related. However, this could reveal some information to your relative about your DNA sequence in the shared regions. For example, if your relative has a specific allele in one of the shared segments, she or he could estimate that there is a 50% chance you have the same allele. If you decide not to participate in relative finding, your relatives will not be able to see this information. However, you will not be able to see your relative finder report.
