Drosophila melanogaster, often referred to as the fruit fly, is an interesting and dynamic insect that provides humanity with important information in the study of genetics. The biological community is extremely devoted to acquiring more information about the genetic process in order to improve the health and existence of humans. The fruit fly may seem like an insignificant specimen; however, it has a surprising number of parallels to the human genome. Humans have 46 chromosomes in which 23 are gametes involved in the reproduction process. Although, the fruit fly has only 4 chromosomes they behave very similarly to humans. This insight has led to new research and development that is continuously explored by scientists all over the globe. The fruit fly has an optimal life cycle which makes it convenient and efficient when studying its genetic information. A fruit fly incurs a life cycle that last approximately one and a half to two weeks. Its life cycle manifests in four phases respectively: egg, larva, pupal, and adult stage. Due to the short amount of time it takes a fruit fly to be reproduced and developed, a plethora of information can be learned in a very short period of time (Lewis 1998). Other benefits of using fruit flies are due to: low cost, production in large numbers, and easy production (Lewis 1998). In laboratory, a dihybrid cross was performed in order to determine the traits exhibited by the F2 generation. Fruit flies have a few physical
