Are your genes unique or do some classmates have the same genes? If you do have the same genes as some classmates, do you at least have a unique combination of genes? 2.Decide on your goals —what you really want to accomplish in 10 to 20 years (My Goals worksheet). 3.Make a conclusion—Will the genes you were given allow you to pursue and attain your goals? How do you know, or what can you do to find out? Use the graphic organizer to plan a persuasive essay to assert your opinion. 4.Write your essay!
15 Class Results: How can you really find out if your genes are good enough for you to accomplish your goals? RESULTS: This is what most students concluded AFTER completing the Observable Traits lab and My Goals worksheet. All students had the same observable traits, but in different combinations. Students decided that their unique combinations of genes would allow them to pursue their goals. So even though most students were glad for their unique combinations of genes, most students concluded that it would be their choices, not their genes, that would determine their success. Not a single student thought his or her genetic makeup was not good enough to accomplish life goals.
