Description:

In this interrupted case study, students read about a college student with phenylketonuria (PKU).  Students learn how diet affects a person with PKU and how PKU is inherited. The case is designed to introduce introductory biology students to the Hardy-Weinberg Principle. Terms of the equation are related to phenotypes and genotypes mentioned in the case. Given the number of people in the population with PKU and assuming the population is in Hardy-Weinberg Equilibrium, students estimate the number of carriers for PKU in the population. Finally, students estimate the probability that a person from this population with PKU would have a child with PKU and the probability that a person from this population without PKU would have a child with PKU.
