Drosophila melanogaster is a group of flies normally known as a common fruit fly, and widely used as an experimental organisms because they possess the ability to breed rapidly, survive in laboratory controlled conditions and have observable genetic mutations that enables different phenotypic differences. Dihybrid crosses shows lineages of two observable characteristics in a species, it was found by Gregor Mendel. This allowed scientists to conclude that genetic information can be inherited from one generation to the other. In this experiment a dihybrid cross involving wild type male drosophilae (cn+/cn+; bw+/bw+) and cinnabar brown female drosophilae (cn/cn; bw/bw) was carried out for a period of four weeks. Each week the parents where disposed
