摘要: Summary Biochemical variants of constituents the blood are considered to be valuable markers genes in studies on population genetics. They being used for that purpose human populations and also laboratory farm animals. The present report is concerned with biochemical dogs. In dog breeding an increasing interest shown origin breeds, their mutual relations, relationship wild canidae. Since biochemically detectable variation can offer information this repect, overall investigation possibilities detection these has been made. study, eleven dogs were found demonstrate clearly genetic polymorphism. systems described. observed frequencies reported.
