In both the Plains Indian and the Finnish Caucasian samples, the percentage of genetic identity shared between any two individuals through common descent was calculated for all possible pairs (related and unrelated) using S.A.G.E. (Case Western Reserve University). The average sharing of descent was 0.003 in the Plains Indians, which is less than the degree of relationship between third cousins. The average sharing of descent between any two Finnish Caucasian individuals was only 0.002.
