QUESTION 1: A couple who are in good health have a baby and are shocked to find that he has cystic fibrosis, an inherited disease. How did the child inherit a life-threatening disease from healthy people (assume that this was not a spontaneous mutation). Why weren't the parents affected by cystic fibrosis? Can this couple give birth to a child without cystic fibrosis? Why or why not?

QUESTION 2: Allison is driving with her parents, Kate and Bob, when they get in a serious car accident. At the emergency room, her doctor (you) tells Allison that her mother is fine, but her father has lost a lot of blood and will need a blood transfusion. Allison volunteers to donate blood, and you tell her that her blood type is AB. Bob is type O. (1) Can Allison donate blood to Bob? Why or why not? (2) Allison, who is a biology student, begins to wonder if she is adopted. What would you tell her and why?

QUESTION 3: When a person is an 'albino', they have very pale (almost white) skin, hair, and eye color. Yet, skin color, eye color, and hair color are controlled by 3 different genes. How do you think a single mutation in a person can cause all three of these traits to be affected? (Hint: see Epistasis in notes)

QUESTION 4: Any Spring Break Plans?
