THE GENETIC AND CYTOGENETIC LOCALIZATION OF THE THREE STRUCTURAL GENES CODING FOR THE MAJOR PROTEIN OF DROSOPHILA LARVAL SERUM

1 Genetics Laboratory, Biochemistry Department, South Parks Road, Oxford OX1 3QU England

The alpha, ß and gamma polypeptides that make up Drosophila Larval Serum Protein-1 seem to be coded for by genes that have evolved by duplication of a common ancestral gene. We have found variants of all three polypeptides, and these are variants of the coding sequences. The alpha-chain variant mapped to 39.5 on the X chromosome and to the polytene interval 11A7-11B9. The ß-chain variant mapped to 1.9 on chromosome 2L and to 21D2-22A1. The gamma-chain variant was mapped as 0.13 map units from the tip of chromosome 3L or to —1.41 with respect to ru, which has been defined as 0.0, and to 61A1-61A6.
