Abstract
We present data supporting cytogenetic observations on nucleolar domin ance in hybrids between Drosophila arizonae and D. mulleri. Our approa ch was to compare the rDNA restriction patterns between the parental s pecies and their hybrids. Results demonstrated that the minichromosome attached to the nucleolus in hybrid males is derived from D. arizonae .
