8 Extra Questions for Discussion: 1 In this class, who do you think you are genetically most similar to? Why?

9 Extra Questions for Discussion: 2. If a person has free earlobes, it is impossible to predict his or her exact genotype. Why is this?

10 3. Look at classmates’ results for all traits. Do most students have dominant traits, recessive traits, or an approximately equal mix of dominant and recessive? Why do you think this is? Do the data from this lab support your answer to question #1?

11 4. Do the data from this lab support your answer to question #1?

12 5. Does it really matter which traits you have? Why or why not?

13 E. Do any of these traits matter? In other words, can you achieve your goals with the genes you have?

14 Do any of these traits really matter? What is genetic expression? –Y–You have many genes, but only certain ones are turned on (expressed). What is genetic determinism? –t–the idea that your genes control your fate Albus Dumbledore again : “... it matters not what someone is born, but what they grow to be." from Harry Potter and the Goblet of Fire

15 Does your DNA determine who you are? Explain.
