Mendelian Genetics

Objectives for the chapter and helpful videos/songs/charts are listed below. This is not an all inclusive list of the content, but it is an excellent place to start or review! The videos are used as a study tool and may cover more or less than what we will cover in class. I will not test you on anything we did not cover in class, unless stated otherwise.
