Description of Unknown Mutant Allele Phenotype Drosophila melanogaster (fruit flies) are organisms that contain multiple types of mutations. A few examples of these mutations involve eye color, wing formation, body size and body color. When comparing the wild type version of D. melanogaster to mutant D. melanogaster with unknown code 651, it was shown that the mutant contained a mutation in the bristles located on the fly’s thorax and head. These mutated flies have short and curly bristles (Figure 1, A arrows) compared to their wild type counterparts which have long and straight bristles (Figure 1, B arrows) in the same locations. This mutation has led us to

This image correlates with short and curly bristle observations previously stated. Image B is the wild type fly and shows how bristles are typically straight and long. Buzzcut clearly differs in length and structure on the thorax and the head when compared to the Wild-Type side panel (Image B).
