3. Suppose that a population has three genotypes with P(aa) = 0.16, P(aA) = 0.48 and P(AA) = 0.36. Sample n people at random with replacement. Let X be the number of people with genotype aa and Y be the genotype with number of people with genotype aA. What are the marginal distributions of X and Y? What is the probability that P(X= 5, Y = 3), if n = 10? What is the covariance between X and Y, if n = 1?
