【 摘 要 】

We have isolated and purified two parental homodimers and a unique heterodimer of acid phosphatase [coded by Acph-11.05(𝐹) and Acph-10.95(𝑆)] from isogenic homozygotes and heterozygotes of Drosophila malerkotliana. 𝐹 and 𝑆 produce qualitatively different allozymes and the two alleles are expressed equally within and across all three genotypes and 𝐹 and 𝑆 play an equal role in the epigenetics of dominance. Subunit interaction in the heterodimer over a wide range of H+ concentrations accounts for the epigenetics of dominance for enzyme activity.
