Make a Life to Save a Life
In this “clicker case,” students learn about meiosis through the real-life story of a couple who used pre-implantation genetic screening to select an embryo that was a genetic match for an older sibling with leukemia, and thus able to provide a source of bone marrow cells. The case caused a stir in the medical ethics community. Before this, parents had only used pre-implantation genetic screening to select for a baby that would be free from a genetic disorder. Instead, this child was conceived as a treatment for his older sister. The case was developed for use in an introductory biology course. It consists of a PowerPoint presentation (~1.5MB) shown in class that is punctuated by multiple-choice questions the students respond to using clickers. It could be adpated for use without these technologies.
