By means of agar gel electrophoresis, serum alkaline phosphatase of the Japanese quail was separated into two polymorphic regions, and it was found that there existed F-pattern appearing in the fast mobility region (Akp-1) and A, B and C pattern in the slow mobility region (Akp-2) on the anode side. With respect to Akp-2 region, six phenotypes were observed: AA, AB, BB, BC, AC and CC. These phenotypes were shown to be controlled by three autosomal co-dominant alleles: Akp-2A, Akp-2B and Akp-2C. Gene frequencies in the total population were: q Akp-2A, 0.081; q Akp-2B, 0.552; q Akp-2C, 0.367.
