Abstract

A ring-Y chromosome, R(Y)w m, of D. hydei is described which carries a complete set of fertility genes, a NOR region and a small X-chromosomal insertion (w m), which may be used as a marker. The ring has been characterized by various staining techniques. It was derived from a w mCo Y chromosome by X-ray treatment of spermatocytes. Its mode of origin allows to fix the gene order in the distal region of the long arm of the w mCoY chromosome. The white + gene included in the ring shows a new type of position-effect variegation which is described and discussed in the context of an earlier hypothesis on a dual function of the white locus.
