Natural and Sexual Selection of Vestigial and Wild Type Drosophila melanogaster Abstract In this experiment‚ vestigial flies as well as wild type flies were used to create some diversity as well as test one of our hypotheses. Our hypotheses are as follows; 1) The wild type flies will have a greater relative fitness compared to the vestigial flies based on only sexual selection. The wild type has a relative fitness of 1 since it has fully functional wings. Vestigial Winged flies are not as sexually
