Two Peas in a Pod
A Case of Questionable Twins
Based on an actual event, this case study focuses on some of the problems associated with reproductive technologies. It tells the story of the "Joneses," who after in vitro fertilization treatment, discover that their fraternal twins are less similar than one would expect two brothers to be. Students work in teams to unravel the mystery using DNA profiling. Related issues that can be explored include the right to medical information, the implications of human error, and racism.
