Determine your imaginary person’s expressed traits based on the cards in your envelope.

Which Traits will your Imaginary Offspring get? Pair up with another student. You will be creating an imaginary offspring with your imaginary parents. Take all of your cards out of your envelope and place them face down, being careful to keep you and your partner’s piles separate. One trait at a time, each partner should select one of the cards for that trait from their pile and reveal the card. (E.g., if you are focusing on ear lobes, each partner should select a pink card from their pile). List the factors that each parent passed on to the offspring. Determine which trait should be expressed by the offspring. Answer the Analysis Questions If time permits, draw a picture of your imaginary people.
