Regarding FTDNA-overall-fits, new logic is even if around three some one each FTDNA-overall-satisfy the other a few, then it is probably be that every three express a common ancestor
- W and you will Z is actually 1 / 2 of-same as both about this area, in which case V, W and you will Z most likely inherited a similar section here from well-known ancestor and the dating should be described just like the triangulated ; otherwise
- W and you can Z are not 50 % of-just like each other about this part, in which particular case V is likely linked to W to the V’s paternal side and you may V is probable regarding Z toward V’s maternal front side, or vice versa , and V’s autosomal DNA here will be phased .
In the example of FTDNA-overall-matches, the fresh new reason is even if three individuals each FTDNA-overall-satisfy the other two, then it’s likely to be that three express a familiar predecessor
- because it is constantly it is possible to than just no less than one of sets are merely half of-identical by accident, particularly if the quantity of SNPs seen in the region in the which the parties is actually collectively homozygous was short; and you will
- as for each may show a similar section which have one of the other a few to the paternal front side and with the 3rd person for the maternal front. Giving a real example, while i consider a good triangular relationships, I always consider my personal GGGgrandfather Parker’s sis and you may my personal GGGgrandmother Keas’s sister exactly who ilies, every one of which have been basic cousins to the other a few, however, just who didn’t have just one common ancestral couples! If a person grabbed DNA from one person in every one of these about three family, two Parkers and you will a great Smith, then each of them since the basic cousins create share of a lot 50 % of-identical countries having both of the rest.
