Relationships much more distant than simply 1C1R and you can 50 % of-1C try grouped with her by people who have an equivalent average common DNA

All of the probabilities was to possess autosomal DNA simply. Delight deduct one X-DNA prior to using the calculator. Including, I would recommend deducting people shared DNA away from areas lower than eight cM you to ily Tree DNA comes with really small markets within overall cM calculations.

Ages and other activities, for instance the possibilities that not familiar high-grandparent otherwise high-grandchild is the DNA suits you receive, would be taken into account.
