The Fruit Fly Experiment is used as a way to introduce students to the study of genetics. It was first used by Thomas Morgan Hunt in 1910. The importance of using fruit flies, also known as Drosophila Melanogaster, is because they are great to work with in a research scenario. They are relatively easy to care for, especially when compared to larger organisms like rats or rabbits. They mate readily, take about two weeks to develop, and carry only four pairs of chromosomes (Shanholtzer, 2012). The prolonged lifespan of an adult fruit fly depends on the temperature of its environment; for example, at 54°F the average fruit fly lifespan is 40 to 50 days (Ashburner, 2012). Female fruit flies are able to mate and lay numerous sets of eggs, allowing the fruit fly population to multiply rapidly. The fruit fly's life cycle begins as soon as the female lays her eggs. The eggs then take about a day to hatch into the next stage, the larva (Shanholtzer, 2012). Once the larva molts and goes through the first, second and third instars, it hatches into the pupa which takes six days to reach the adult stage (Shanholtzer, 2012). Fruit flies normally feast and bask on rotten fruits, although this is possible because they are found on cured vegetables and other foods (Ashburner, 2012). It is common for fruit flies to have red eyes, usually referred to as Wild Type, but they sometimes moult and have brown eyes and are referred to as Sepia (Shanholtzer, 2012). For this experiment, the indicated flies or the F1 generation are hybrids for two traits, normal or black body and wild type eyes, which is dominant, or sepia eyes which is recessive. The F1 generation is the daughter of the parent P1 generation. The P1 generation consists of... half the paper... here's the possibility that the student didn't make sure they had the proper amount of fruit flies, or there may have been a mix-up with the sexes. Some fruit flies may have drowned in the media; there may also have been errors during the estimation for the offspring calculation. For future experiments, another hypothesis could be to take the sex of the fruit fly into consideration, finding out whether or not the traits are sex-linked. Although fruit flies are often overlooked and considered a huge frustration, according to Michael Ashburner, fruit flies are credited with approximately 75% of disease-causing genes in humans (2012). The fruit fly experiment could be used by scientists to gain knowledge and define how human genetics operate. In other words, this experiment can shed light on how certain traits and diseases are transferred from one generation to the next.
