摘要

The α, β and γ 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 α-chain variant mapped to 39.5 on the X chromosome and to the polytene interval 11A7-11B9. The β-chain variant mapped to 1.9 on chromosome 2L and to 21D2-22A1. The γ-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.
