title: A Y-translocation method for localizing enzyme genes on Drosophila polytene chromosomes.
abstract: X-Ray induced translocations between autosomes and the Y-chromosome giving balanced and aneuploid (partially trisomic) male offspring proved useful for a rather precise localization of enzyme loci in the subsections of the polytene chromosomes of Drosophila subobscura.
