4) If a visitor from another planet were to walk into the classroom, will he/she conclude that we all look alike? Support your answer with evidence.

Activity: In pairs, compare yourself to your partner’s traits. List: a.2 inherited traits that you are alike. b.2 inherited traits that you differ by. c.2 non-inherited traits that you are alike. d.2 non-inherited traits that you differ by. Discuss: How did you decide which trait is inherited and which is not?

1. How did it come about that we, human, are both so similar, and also so different from one another? 2. Some human traits are heritable and some are not. Use the Inventory of Human Traits and provide an example of each type of trait. Journal:

3. Why is it that you look different from your parents?

Apply: Some human traits are influenced by both genes and the environment. Provide an example of a trait that reflects an interaction between genes and the environment. Predict: For those traits that are heritable, what is the source of the variation?

! 9. How many traits do we need to examine in order to identify any student in the class as unique? Let’s compare to one person… -Everyone stands, one volunteer is in the front. -We compare one trait at a time. -Once you find a difference from the volunteer, you sit down. - We continue until the volunteer stands alone.
