The above numbers are based exclusively on the comparison of their Y-DNA results, which show 2 mismatches.

However, these results can be refined if their paper trail indicates that no common ancestor between Wright #26651 and the other participants could have lived in a certain number of past generations.

Since each marker has a different mutation rate, identical Genetic Distances will not necessarily yield the same probabilities. In other words, even though Wright #26651 has a Genetic Distance of 2 from both Wright #20791 and Wright #20201, however, the same Genetic Distance has different probabilities because the distance of 2 was prompted by mutations in different markers, with different mutation rates.
* The FTDNATiP™ results are based on the mutation rate study presented during the 1st International Conference on Genetic Genealogy, on Oct. 30.2004. The above probabilities take into consideration the mutation rates for each individual marker being compared.
