Is it possible to count the number of PKU carriers in a population? Why or why not? 3. If 50 of the 500,000 people in Atlanta have PKU, how many people are carriers? 4. In Atlanta, if a woman with PKU marries a man without symptoms of PKU, what is the chance that they will have a child with PKU? 5. If two people without symptoms in Atlanta have a child, what is the chance that the child will have PKU?
