Sexual interactions with same-sex are widespread among animals, but until now the puzzle remains. One of the animals that exhibit this behavior is the Drosophila Melanogaster or fruit flies, in which this paper will be focusing on. Fruit flies have the ability to reproduce rapidly, tendency for males to mate intensely with immature males (Dukas, 2010). Over the past few years, since fruit flies’ genome are simple, researchers made a constant effort in studying the same-sex behavior in Drosophila Melanogaster or fruit flies and how a particular mutation in a gene was involved in the male-to-male courtship due to poor recognition of the opposite partner (Everaerts, Lacaille, & Ferveur, 2010). Bailey, Hoskins, Green, and Ritchie (2013) confirm

We will randomly collect 140 wild types of Drosophila Melanogaster between August 20-24, and will house it to the lab. Once collected, we will execute three treatments for the fruit flies. Ensure to carry out the experiment under the same nutritional food and desirable environmental conditions since, fruit flies only have an average life of a month. The first trial will consist of 3 males and 3 females isolated in a 6 cm cork stopper glass bottle and measure the mating experience of each focal male with spot checks once every hour (Han & Brooks, 2015). For trial two, after a week of equal ratio treatment, in day 8, focal males will be assigned randomly with 4 males to 2 females and 2 males to 4 females sex ratio treatment. After 7 days we will have to repeat the experiment but this time each focal males will be isolated within 24 hours for 7 days and measure the mounting events. We will use a different method for measuring the frequency of SSB and its impact using a behavioral assay on mating success in a biased male-ratio. For treatment three, 90 males will be place into 1 to 1 ratio in a 24 hour isolation period for 7 days with varying levels of food availability. After 7 days, we then have to place a focal male to 3 random males for 2 days. Immediately, after 2 days of isolation of the focal male, we
