Differences in the quinacrine staining of the chromosomes of a pair of sibling species: Drosophila melanogaster and Drosophila simulans

Abstract

The patterns of intense fluorescence after staining with quinacrine dihydrochloride were studied in both the polytene chromosomes and mitotic chromosomes of a pair of sibling species, Drosophila melanogaster and D. simulans. Consistent differences between the two species were found in the pattern of fluorescence of both polytene and mitotic chromosomes. In addition, it was discovered that our stock of D. melanogaster (Oregon-R) is polymorphic at one autosomal position for the property of intense fluorescence after quinacrine staining. On the basis of these findings, the usefulness of quinacrine staining in the study of the cytogenetic structure of evolutionarily interesting populations is discussed.
