Choose the traits of the offspring by flipping a coin twice for EACH TRAIT! Pay attention to the side and order in which the coin lands, and circle the appropriate offspring genotypes based on the locations below! Heads then Heads: Top Left Box Heads then Tails: Top Right Box Tails then Heads: Bottom Left Box Tails then Tails: Bottom Right Box Complete the Offspring Chart based on what was circled in the Punnett Squares. Be sure to come up with an appropriate name for the offspring. **10 Points** To determine gender, complete a Punnett Square, and flip a coin the same as above! **5Points** Create a full color drawing of the offspring character, complete with the character s name as well as the parents names! **20 Points** **100 Points Total**
