The microbiome, which is all the genetic material of microorganisms in a particular environment, has a significant impact on the host. This field of study reveals answers to questions relating to bacterial significance and the relationship between the two and the microbiome, which in turn can affect the phenotype of the host organism. Drosophila melanogaster has been a model species for microbiome work for years because it possesses a microbiome that can be easily manipulated due to the simplicity of the microbiome's composition. Here, we utilize the two dominant species found in the gut microbiome of the fruit fly, acetic acid bacteria and lactic acid bacteria, to determine genetic trends relating to the effect of choice on the microbiome of the fruit fly and its relationship to the concentration of both of these types of bacteria. We do this by simulating a scenario where the fruit fly is presented with the choice between the two types of bacteria and discussing the resulting projected data.
