To some extent, the permeability of these categories in the intervening decades helped to reify the biological distinctions, generating a taller elite and a shorter underclass, but with little relation to the gene pools that had existed a few centuries ago.
U određenoj mjeri, propusnost od tih kategorija u nadolazećim desetljećima pomogla da popredmetiti biološke razlike, stvarajući visoke elite i niže podređene, ali s vrlo malo veze s genskim bazenima koji su postojali prije nekoliko stoljeća.
