3. Oh Me, Oh Mei-osis: Just Like Me… Answer the following on your paper:
How many people in your class shared all of your traits?
How many people in your class shared zero traits?
How do your results compare to your prediction? Explain your answer.
In this survey, we compared only a handful of the over 100,000 traits that make up the human genome. Based on this and your results, what do you think are the chances that you would find another person in your school, in this country, or even the world, who has the exact same traits as you? Discuss.
You should observe that it is highly unlikely that anyone in the world will have the same traits as you do, unless of course, you are a TWIN!
