“How can someone predict the traits of offspring?”

By using punnet squares and genetic information that has already been discovered.

Why is it important to study the principles of inheritance (how traits are passed on to offspring)?

So that we can see what the offspring will look like as well as determine if they will have a disease or disorder.
