Distribution of Gm and Inv factors in two samples of the Greek population.

Gm and Inv polymorphism has been investigated on a sample of the general Greek population (N = 256) and on a sample of the Achaia population of Northwestern Peloponnusus (N = 150). The estimated frequencies were, respectively in the two groups: Gm1, 0.156 vs. 0.180; Gm1,2,0.010 vs. 0.017; Gm4,12, 0.834 vs. 0.803; Inv (+1), 0.125 vs. 0.140.
