Summary The cholinesterase activity in horse serum was shown to be controlled by four co‐dominant autosomal alleles, Ch A , Ch B , Ch c and Ch D . The respective alleles controlled an activity of approximately 40, 76, 126 and 155 units. Nine phenotypes with different enzyme levels were distinguished. Family data with 11 stallions, 108 mares and 128 offspring were consistent with the genetic theory. The gene frequencies in the North Swedish horse breed were 0.32, 0.42, 0.13 and 0.13, respectively.
