Drosophila melanogaster, also known as fruit fly, is a basic model organism for developmental biology and other areas of genetics research. This is so because Drosophila have a two week generation time, are cheap and easy to raise on a man-made diet. The life cycle of Drosophila includes these stages: embryo, three larval stages, prepupal, pupal, and adult. After the Drosophila embryo is fertilized, it will enter into nuclear division. The result of nuclear division is the formation of a blastoderm. In the blastoderm stage, positional information and cellularization is occurring in the embryo (Purves, et al., 1998). From there, the embryo enters into germ band extension where gastrulation occurs. The early stages of organ development are
