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.
