However, these results can be refined if their paper trail indicates that no common ancestor between Marcel W. Landry and L-4, L-6, L-8, L-9 could have lived in a certain number of past generations.

If you don't know this information for a fact, do not change the "1" in the box in the next paragraph. However, if you have the information, please enter in the box and click on the recalculate button.
Marcel W. Landry and L-4, L-6, L-8, L-9 did not share a common ancestor in the last XXX generation(s). (Because the important factor in calculating the time to the Most Recent Common Ancestor is the number of generations between which mutations could take place, the number of years per generation is irrelevant in FTDNATiP™ calculations.).
 

* 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.
 

Since each marker has a different mutation rate, identical Genetic Distances will not necessarily yield the same probabilities. In other words, even though someone has a Genetic Distance of 1 from Marcel W. Landry, someone else with the same Genetic Distance may have different probabilities, because the distance of 1 was prompted by mutations in different markers, with different mutation rates.
