Hot Cheeto Research Paper

The affected phenotype in the mutant hot cheeto is the bristles. The affected bristles are gnarled, dark, and bending to the side of the scutum. The tip of these bristles look melted. The sizzled appearance of the phenotype makes the name of hot cheeto appropriate for this mutant. The bristles of the wild type Drosophila melanogaster are long, slick, and black. The posterior scutellar bristles in D. melanogaster are two long bristles attached to the end of the scutellum and projected in an outward V-shape. Yet, in hot cheeto, the V-shape projection is not present because the short bristles curled to opposite sides of the scutellum. Humeral bristles, dorsocentral bristles, notopleural bristles, anterior scutellar bristles, orbital bristles, and ocellar bristles are all affected by this mutation. This mutation affects the phenotype equally in both female and male mutants. However, the mortality rate in hot cheeto females was greater than males. The larva of both the wild type and the mutant …show more content…
The singed (sn) gene is responsible for producing healthy bristles. Mutations to this gene can create distorted bristles and female sterility. This gene can be found in 1-21.0 (Guild et al. 2005). The forked (f) gene might be responsible for the proper elongation of bristles. Mutation of this gene lead to short bristles. This gene is located at 1-56.7 (Okenve-Ramos and Llimargas 2014). A mutation to the spineless (ss) gene can reduce the size of bristles. The location of the gene is at 3-58.5 (Kuzin Doszhanov and Mazo 1997). The shaven (sv) gene if mutated produces Drosophila melanogaster without bristles. Located at 4-3.0 (Fu Duan Frei et al. 1998). A mutation to the gene frizzled generate wavy and short bristles. Also bristles with this mutation are bent to opposite sides of the scutum. This gene is located at 3-41.7 (Adler Vinson et. al.
