Question 2: People with albinism have little pigment in their skin, hair, and eyes. The gene that governs albinism has two forms (alleles), which are denoted by a and A. Each person has a pair of these genes, one inherited by from each parent. A child inherits one of each parent's two alleles, independently with probability 0.5. Albinism is a recessive trait, so a person is albino only of the inherited pair is aa. a) b) C) Beth's parents are not albino but she has an albino brother. What types must Beth's parent's be AA? Ad? on? Which of the types AA, Aa, 00, could a child of Beth's parents have? What is the probability for each type? Beth is not albino. What are the conditional probabilities for Beth's possible genetic types? Assume that the probabilities for Beth's genetic types are given by part (c) above. Beth marries Bob who is albino. d) e) o What is the conditional probability that a child of Beth and Bob is non-albino if Beth is of type Aa? What is the conditional probability that a child of Beth and Bob is non-albino if Beth is of type AA? Beth and Bob's first child is non-albino. What is the conditional probability that Beth is of type AA? m: Make a probability tree
