A group of 1916 Russian men donors was studied for 15 electrophoretic blood protein systems, coded by 22 protein loci: Transferrin (Tf), Haptoglobin (Hp)--2 loci, Group-specific component (Gc), Hemoglobin (Hb)--2 loci, Lactatdehydrogenase (LDH)--2 loci, Malatdehydrogenase (MDH), Erythrocyte esterase (Est)--4 loci, Albumen (Alb), 6-phosphogluconatdehydrogenase (6 PGD), Phosphoglucomutase (PGM)--2 loci, Esterase D (Est D), Adenosindesaminase (ADA), Acid Erythrocyte phosphatase (AcP), Glutamic transaminase (GPT) and Glioxalase-I (GLO-I). Ten loci were defined as polymorphic, the level of heterozygosity for cumulative loci was 0,1435 +/- 0,003. Moscow population was compared to major human races for the set of genetic characters--heterozygosity, correlation coefficient of single locus heterozygosity, a genetic distance. It has been shown that the extent of relation of ethnic groups to Moscow population decreases as follows: Caucasoids, Mongoloids, Negroids.
