Textbook Question
Chapter 1, Problem 15PDQ
If you knew that a devastating late-onset inherited disease runs in your family (in other words, a disease that does not appear until later in life) and you could be tested for it at the age of 20, would you want to know whether you are a carrier? Would your answer be likely to change when you reach age 40?

. If your father were diagnosed with an inherited disease that develops around the age of 50, would you want to be tested to find out whether you would develop this disease? If so, when would you want to be tested? As a teenager or sometime in your 40s? If not, would you have children? (
In a paternity suit, a woman with type O blood claims that a man with type AB blood is the father of her type O baby. List the genetypes of the mom, man, and baby. Can the woman prove he is the father or can he is not? Why or why not? If the accused man was type A insyead of type AB, what would be his possible genotypes? Could the woman prove he is the father? Can the man prove he is not the father? Why or why not?
