Two Peas in a Pod? A Case of Questionable Twins

Journal of College Science Teaching—February 2004

Based on an actual event, this case study focuses on problems associated with reproductive technologies. It tells the story of the “Jones” who, after in vitro fertilization treatment, discovered that their fraternal twins were less similar in appearance than one would expect two brothers to be. Students work in teams to unravel the mystery using DNA profiling. Related issues include the right to medical information, the implications of human error, and racism.
