Chapter 7
Heredity and Inheritance, Evolution
Why do you have your mother's eyes but your grandfather's chin? Children resemble their parents, yet no two are exactly alike. In this chapter you see how variation arises, follow Mendel's experiments with pea plants, learn how genes control traits, and find out how the sex of a baby is decided. Python crosses pea plants for you and counts the ratios Mendel found.
