“Hybrid” X-Y translocation chromosomes of Drosophila hydei and D. neohydei

Abstract

The Y chromosome of Drosophila carries fertility genes which, in part, develop lampbrush loops during the meiotic prophase. Hybrid males from crosses between D. hydei and D. neohydei are fertile although the morphology of the lampbrush loops differs between both species. With the aid of X ray induced “hybrid” X − Y translocation chromosomes the question has been studied whether Y chromosomal genes of D. neohydei can substitute deletions in the Y chromosome of D. hydei. Although the induction of translocation chromosomes almost regularly results in an inactivation of the translocated Y fragment within a few generations, one case of successful complementation has been demonstrated. Furthermore, a new lampbrush loop pair has been detected in D. neohydei which is morphologically similar to the “nooses” of D. hydei. Preliminary evidence for the location of the lampbrush loops on the Y chromosome of D. neohydei is discussed.
