Regulation of the rate of RNA synthesis in Drosophila melanogaster diploid cells with 1, 2, 3 and 4 nucleolar organizers is studied. The data indicate that in flies with the redundant nucleolar organizer (NO) content extra NOs are eliminated by the 18th generation and the level of rRNA synthesis is typical for control wild stock flies. In flies bearing single NO on the Y chromosome, extra rDNA replication does not occur and rRNA genes deficiency by the increased rRNA synthesis is compensated. It is suggested that in genotypes studied the rate of rRNA synthesis depended on sex chromosome quantity per genome.
