Two separated nucleolus organizers on the Drosophila hydei Y chromosome.

U Schäfer, W Kunz.   

Abstract

By genetical, cytological, and filter saturation hybridization methods it is shown that the Y chromosome of Drosophila hydei contains two separate nucleolus organizers, one on the short arm, the second near the tip of the long arm.
