This investigation involves the cytogenetics of three strains of field-collected, wild-type Illinois Drosophila melanogaster. These three strains were collected from Charleston, Channahon, and Olney, Illinois, in 1967. The purpose of this study was to compare cytogenetically these three strains and to determine if there exists differences among them. First, the chromosomes themselves were studied for the purpose of identifying the four chromosomes of D. melanogaster by their characteristic banding patterns. Then, the chromosomes of the three strains were examined for chromosomal aberrations, principally inversions. The cytogenetics of the chromosomes of the three strains were then compared and contrasted. Photographs were taken of the chrom...
