Rules for Group Review
You must work with your group.Only one person may answer for your
group.You may not talk during other groups’
turns or your group will lose points.If you repeat an incorrect answer, your
group will lose points.You may not use anything during Group
Review except your brains.If voice levels cannot be controlled, we
will stop playing and instead have a pop quiz.

Bonus Round!!!!
At the end of each scoring round, there will be an opportunity for “Garbage Ball”.
For this, one member from each team will be given the chance to try to shoot the Garbage Ball into the small garbage can.
If the team member makes the shot, the team earns that round’s points as extra points.
In the case of excessive cheering, teams can be penalized.
In the case of excessive insulting, teams can be penalized.

Final Question!!!!
Talk to your group to decide how many points you want to wager.
If you get the Final Question correct, you will add the wagered points to your score.
If you don’t, you will lose the points.

Final JeopardyGenetics and Heredity
Everyone in Squidward’s family has light blue skin, which is the dominant trait for body color in his hometown of Squid Valley. His family brags that they are a “purebred” line. He recently married a nice girl who has light green skin, which is a recessive trait.
Create a Punnett square to show the possibilities that would result if Squidward and his new bride had children. Use B to represent the dominant gene and b to represent the recessive gene.
What is the probability of having green skinned offspring?
