Abstract
By means of agar gel electrophoresis, acid phosphatase in various organs of the Japanese quail was separated into two polymorphic regions (Acp-1 and Acp-2), and it was found that there existed AA, AB and BB phenotypes in the slow mobility region (Acp-2) on the anode side. These phenotypes in Acp-2 region were shown to be controlled by two autosomal codominant alleles: Acp-2Aand Acp-2B. Gene frequencies in the total population were: Acp-2A, 0.42; Acp-2B, 0.58.
Acid phosphatase activity of embryo is detectable from 5th day of incubation and increases as the days of incubation increase. From crossing experiment, it was recognized that gene controlling acid phosphatase of embryo is the same gene that controls acid phosphatase in various organs of adult (Acp-2).
