Abstract

To examine the genetic composition of proximal heterochromatin in chromosome 2, the detachment of compound second autosomes, for generating proximal deficiencies, appeared a promising method. Compound seconds were detached by gamma radiation. A fraction of the detachment products were recessive lethals owing to proximal deficiencies. Analysis by inter se complementation, pseudo-dominance tests with proximal mutations and allelism tests with known deficiencies provided evidence for at least two loci between the centromere and the light locus in 2L and one locus in 2R between the rolled locus and the centromere. The data further demonstrate that rolled, and probably light, are located within the proximal heterochromatin. Thus, functional genetic loci are found in heterochromatin, albeit at low density.
