Evidence is presented to show that “Caucasian” genes ( B, K, Lu a , r, AK 2 , P c , and Gm 3,5,11 ) in hybrid North American Indian populations follow a Poisson distribution. A method of determining the maximum amount of admixture, given an observed count of Caucasian genes, is developed. Establishment of the upper limit of admixture is suggested as the preferred estimate of gene flow in situations where absence of specific genes at particular loci precludes the calculation of a mean admixture estimate.
