About this unit
Have you ever been told that you have your mother's eyes or grandfather's nose? Learn why traits run in families and how they're passed on. We'll look at Mendel's model of inheritance, see how it's been revised and extended in the past 150 years, and get a sneak preview of the modern concept of a gene.
