Poblem:
Question 1: How does incomplete penetrance, variable expressivity, pleiotropy, and genetic heterogeneity affect the severity of a disease in a family?
Question 2: Why might the weight of the rat pre-castration be important during the dissection lab? (Hint: how do the hormones have an effect on the rat pre vs post-castration?) Would you expect it to change? If so, in what way and why?
