Polymorphism for E2 locus of human serum cholinesterase was studied in populations of evenks and yakuts of Krasnoyarsky region by the method of starch gel electrophoresis. Thee frequencies of C5+ phenotype correspond to C5+ frequencies in other mongoloid populations of Siberia. The activity of cholinesterase was determined by semiquantitative technique. Three individuals with a sharply decreased cholinesterase activity have been revealed.
