Baker (1971) presented genetic evidence that the inviability of In(1)scL8/O and scS1/O males in Drosophila melanogaster is due to position effect suppression of ribosomal RNA cistrons. Although scL8/O and scS1/O males are inviable, scL8/scL8 and scS1/scS1 females are viable. We therefore asked the following question: Is scL8/O or scS1/O viable when part of a gynandromorph? In other words, is position effect suppression of rRNA genes autonomous or non-autonomous in gynandromorphs? In this paper preliminary evidence is presented which suggests that position effect suppression of rRNA cistrons is non-autonomous. The evidence is that scLS/ or scS1/O (male) parts of gynandromorphs are not only viable but normal in appearance.
