Effect of mutation on mating propensity in Drosophila biarmipes

By using multiple-choice technique, mating success between purple eye colour mutant and wild type D. biarmipes was studied in an Elens-Wattiaux mating chamber. Red eyed (wild type) males were more successful in mating than mutant males. However, mutant females were more receptive than wild females. The results suggest that purple eye colour mutation affects mating propensity in D. biarmipes.
