A comprehensive Grade 5 science lesson on heredity and genetics, focusing on North Carolina wildlife. Students will distinguish between inherited traits and learned behaviors, analyze population data, and receive an introduction to Punnett squares.

Common Misconception Alert!
"Students often believe that if an animal acquires a trait (like a bear losing a limb or a human getting a tan), they will pass that trait to their offspring. Remind them that only changes to the germ cells (DNA) can be passed on. Environmentally acquired physical traits are not inherited!"
