How accurate is Family Finder’s Relationship Range?
The Family Finder’s Relationship Range is a high confidence prediction of the possible relationships between two people. Because it takes into account a combination of factors, including the total number of shared DNA segments (blocks) as well as the total number of centiMorgans, the result is a highly accurate range of relationships. Depending on how well the DNA matches based on these factors, the range may be large or small. The Relationship Range is just as accurate whether it shows a small range of potential relationships or a large one.
