Acid phosphatases in Drosophila auraria.

A study was carried out dealing with the acid phosphatases, in larvae, pupae and adults of Drosophila auraria. The most interesting finding is that the acid phosphatases are observed in 3 different phenotypes appearing as groups of 3 bands of different mobilities in the homozygotes and giving a 5 band phenotype in the heterozygote. A hypothesis is discussed in an attempt to explain the phenotypes observed and their variation during the development of the species.
