Heredity: Coin Toss
... Background Information: Genetics is the study of heredity, or passing on of traits from one organism to its offspring. For each trait, every organism has a pair of factors, or units of heredity, called genes. These units of heredity come from the parents of the offspring. One of each pair comes from ...

Lesson 1: How are traits inherited?

Adaptations can be structural, functional, or behavioral. a. The flap of skin that enables a flying squirrel to glide through the air is an example of a(n) ...
