The common fruit fly, Drosophila melanogaster, is the most st ied organism in genetic research because it is small, easy to grc and reproduces rapidly. The length of the thorax (where the win and legs attach) in a population of male fruit flies is approximat Normal with mean 0.800 millimeters (mm) and standard deviat 0.078 mm. Exercises 11.20 to 11.22 use this information. 11.20 Choose a male fruit fly at random. The probability th the fly you choose has a thorax longer than 1 mm is about (a) 0.995. (b) 0.5. (c) 0.005.
