Heredity and Genetics
When you go to a physician for the first time, they always get a record of your family history. They find out who in your family had cancer, heart disease, asthma etc. Why do they do this? It turns out, some diseases have a heredity component, meaning that if your parents have a specific disease, they pass down genes to you that make you more likely to develop the same disease. Today, you will be playing the role of the doctor.
