Phenylketonuria (PKU) is one of the most common inherited disorders — occurring in approximately 1 in 10,000 babies born in the U. S. It occurs in babies who inherit two mutant genes for the enzyme phenylalanine hydroxylase. This enzyme normally starts the process of breaking down molecules of the amino acid phenylalanine that are in excess of the body's needs for protein synthesis. In the United States, approximately 1 person in 50 has inherited a PKU allele. This means that some 5 million people in the U.S. are "carriers". Two individuals that did not have Phenylketonuria had two children. They had one child who inherited phenylketonuria and another child that did not have the disease. If they have a third child, what is the probability that that child will have PKU? 50% 25% 67% 100% 75%

Phenylketonuria (PKU) is a disorder characterized by an inability to breakdown phenylalanine, which is caused by a recessive allele. The frequency of this disorder is 1/10,000 in the U.S. Show your work for all the points. What is the frequency of individuals in the U.S. born with PKU?
Phenylketonuria occurs in about 1 in 10,000 newborns. What is the approximate frequency of carriers (heterozygotes) in the population? Select one: 1 in 100 1 in 10,000 1 in 5,000 1 in 50 1 in 20,000
