5. If a protein called phenylalanine builds up in the body, the person has a disease called phenylketonuria (PKU). PKU causes irreversible mental retardation. Normal phenylalanine function is dominant to abnormal phenylalanine function, Use the letter N for dominant and the letter n for recessive to answer the following questions. a) Fill in the following chart with respect to phenylalanine function: Possible Genotypes Phenotype s A" a rerm. nr . iwdte b) Is it possible for two people with normal phenylalanine function to have a child with abnormal phenylalanine function? Why or why not? c) Fortunately, abnormal phenylalanine function can be treated with a special diet and chemicals to help break down phenylalanine (if the individual is diagnosed early). A person with abnormal phenylalanine function marries a heterozygous person with normal phenylalanine function. What are the chances of their children having abnormal phenylalanine function?
