Genetics Pre-test

The study of genetics allows us to analyze the patterns by which traits are passed down from parents to their offspring through their genes. These patterns can be used to see simple things like the color of a person’s skin or the color of their hair, but more importantly, it can be used to identify terminal illnesses early in their development. What do you know about genetics? Let’s find out!
