The common fruit fly drosophila melanogaster is the most studied organism in genetic research because it is small, easy to grow, and reproduces rapidly. the length of the thorax (where the wings and legs attach) in a population of male fruit flies is approximately normal with mean 0.800 millimeters (mm) and standard deviation 0.078 mm. draw a normal curve on which this mean and standard deviation are correctly located. (hint: draw an unlabeled normal curve, locate one, two and three standard deviations away from the mean, then add number labels on the horizontal axis.)
