Dr. Brooke Bourdelat-Parks and Sonya Greene revamped the Mendelian Genetics laboratory component. The changes were implemented in the fall of 2004. Case-based activities were added to the lab to give the lab a more interactive nature. Prevalence of different diseases, how to draw pedigrees, how to calculate probabilities based on whether a disease is dominant or recessive, and genetic abnormalities are examples of the types of cases that were added.
