. Refer back to the scenario of the previous exercise. In the figure below, the genotypes of both
members of Generation I are known, as is the genotype of the male member of Generation II. We
know that hamster II2 must be black-colored thanks to her father, but suppose that we don’t know
her genotype exactly (as indicated by B- in the figure)
(a) What are the possible genotypes of hamster II2, and what are the corresponding
probabilities?
(b) If we observe that hamster III1 has a black coat (and hence at least one B gene), what is the
probability her genotype is Bb?
(c) If we later discover (through DNA testing on poor little hamster III1) that her genotype in
BB, what is the posterior probability that her mom is also BB?
