The first case study is modified from the case study, The Death of Baby Pierre. I changed the name of the child to make it less likely for my students to search and copy the answers to the questions, from the answers online. So, if my students have decided to look at my blog, they have found the source of Case Study #1, and they can check their answers. For the Hardy-Weinberg equation, I re-wrote that section of the case study, as a guided approach to the answers, because my students have had minimal exposure to the application of quadratic equations. Some of my students still find the equation difficult to understand, but having a question that guides them through the equation, as least makes them somewhat aware that there is a way to apply genetic principles to populations, as well as individuals.

Case Study #1 is about the genetic inheritance of tyrosinemia. Here is a video about a victim of this disorder. The first 5 minutes is informative and I can show that part to my students. The ending includes the family drama of the disorder.

The genetics project consists of three directed case studies. For these case studies, you will complete an introductory activity, which is included with this packet. You will receive a “mark of completion” in the teacher’s grade book for having completed the introductory activity, and then you will receive the information that is required for analyzing the cases: The Death of Baby Jeanette, Huntington’s Disease – A Family History, and Hemophilia: The Royal Disease. For these cases, you will be drawing, organizing, and analyzing pedigrees, demonstrating your knowledge of Mendelian genetics, and answering structured questions that are designed to show, in your answers, your understanding of basic genetic principles. This also includes your knowledge of the DNA molecule and its role in inheritance. You will also be playing the role of decision maker as you analyze and state your findings about the cases. So, here we begin:
