10. A population geneticist collected 400 deer mice from the wild. All have normal ears. She raised about 800 animals in each of the following four generations (random mating) and found that all except one male in the fourth generation had normal ears. This male was earless but was otherwise wild-type and fertile. (a) Suggest 3 possible causes that could lead to the appearance of this earless male. (b) What kinds of experimental crosses would you carry out to distinguish between these three alternatives?
