• How to play…– Don’t play like Jeo_ _ _ _ y.– Class should be divided into several small

groups.– Groups should use science journal (red slide

notes), homework, and other available materials to assist you.

– Groups can communicate quietly with each other but no sharing answers between groups.• Practice quietly communicating right now?• Practice Communication Question:• Your group gets to order one pizza and you can

have two toppings. What does your group want?

• Use the following for questions 19-20:• Having a widow’s peak like Wentworth Miller

is dominant. Not having a widow’s peak, like Rihanna, is recessive.

19

• Look at the phenotypes of Beyonce and Jay Z. REMEMBER: Having a widow’s peak is dominant. Not having a widow’s peak is recessive.

• If these two had children, could they have children with a widow’s peak? Why or why not? Be sure to also use a Punnett Square to explain your answer.

Final Question

• Mr. Krabbs and his wife recently had a Lil’ Krabby, but it has not been a happy occasion for them. Mrs. Krabbs has been upset since she first saw her new baby who had short eyeballs. She claims that the hospital goofed and mixed up her baby with someone else’s baby.

• Mr. Krabbs is homozygous for his tall eyeballs, while his wife is heterozygous for her tall eyeballs. Some members of her family have short eyes, which is the recessive trait.

• A. Did the hospital make a mistake? Explain your answer.
