Relationship Estimators

Each company provides an estimate on the the most likely relationship you have with a match. They all note that, with the exception of parent/child or identicals (twin, triplets, ect), the predicated relationship has a range of possibilities. The relationship estimate for the same match can be different at each company for several reasons:

• Different Chips (different places on the DNA is tested)
• Different Algorithms
• Native vs Transfer Sample (did you test directly or transfer a test in?)

Third party tools try to improve the accuracy of these estimates, which improves the accuracy of figuring out where someone fits in a tree.

Third Party Tools :

• DNA Painter’s Shared CM Project
• DNAAdoption’s Relationship Estimator
• Add more about each tool
