People for which the same situation applies for their 1024 ancestors of ten generations ago would have a coefficient of r = 2 −10 = 0.1%. If follows that the value of r can be given to an accuracy of a few percent if the family tree of both people is known for a depth of five generations, and to an accuracy of a tenth of a percent if the ...
Consanguine marriage is marriage between individuals who are closely related. Though it may involve incest, it implies more than the sexual nature of incest.In a clinical sense, marriage between two family members who are second cousins or closer qualifies as consanguineous marriage.
