Gene regulation in Drosophila mulleri, D. arizonensis, and their hybrids: The nucleolar organizer*

RESUMO

Typically, Drosophila have nucleolar organizer regions (NORs) confined to the sex chromosomes. Salivary gland cells of hybrids between Drosophila mulleri females and D. arizonensis males exhibit features in nucleolar organizer regulation that differentiate the species on one hand, and which show an interplay between the X and the microchromosome on the other hand.
