Two regions of acid phosphatase activity were resolved from liver extracts of chickens by starch gel electrophoresis. With respect to Region II, three phenotypes have been observed. These phenotypes were shown to be controlled by a pair of autosomal codominant alleles; Acp-2A producing a fast moving band and Acp-2B producing a slow band. Heterozygotes have, in addition to the fast and slow enzymes, a hybrid enzyme of intermediate electrophoretic mobility.
