A biologist studying a population of birds comprised of some individuals with long-tailed and some short-tailed individuals. She is interested in whether a population of birds is randomly mating or if the birds are preferentially mating with their own tail type. In this species tail length is controlled by a single gene with two alleles (T=long, t=short) where the long tail is dominant. To examine this aspect the scientist will use controlled populations of birds and assess the results of the mating that occurs. Which of the following would be an appropriate null hypothesis?

A. The population of birds is mating randomly.

B. If the population of birds is mating randomly the length of the tails will change.

C. If the population of birds is mating randomly the gene frequencies will change.

D. If the population of birds is mating randomly the gene frequencies will stay the same.

E. If the population of birds is mating randomly the gene T will go to fixation and all birds will have long tails.
