The mutant fs(1) 1163 of Drosophila melanogaster, which was isolated by Gans et al. (1975) is a recessive homozygous female sterile at 18 ยฐ C and a dominant female -sterile at 29 ยฐ C. We reported previously that there are reduced quantities of the largest of the three yolk polypeptides in Drosophila

## Abstract In contrast to previous findings, three major yolk proteins have been identified in the oocytes and eggs of Drosophila melanogaster. They are also present as major proteins in the haemolymph of mature females and in trace amounts in the haemolymph of young females; the male haemolymph l
The regulatory sequences leading to the ovarian and fat body expression of yolk proteins 1 and 2 (YP1 and 2) of Drosophila melanogaster have been characterised in some detail. These genes (yp1 and yp2) share many enhancer elements, and some important regulatory sequences lie within the coding region
