Summary A genetic variation was found in pancreatic esterases of Japanese quail which appeared to be arylesterase. It was found on the cathode side in the agar gel electrophoresis. Three phenotypes, A, B and AB, were observed. These phenotypes were shown to be controlled by one autosomal locus, designated as Es‐4 , with co‐dominant alleles Es‐4 A and Es‐4 B .Es‐4 esterase isozymes were detected in all the individuals from about 4 days of age, but the activity was very weak. However, it gradually increased to reach a level almost the same as that of a mature quail from about 15 days of age.
