1. Pass It Down… Course: Biology Unit: Genetics Developed by Students at Glencoe High School

2. Description: Activity #1: Frequency of Traits Can you roll your tongue? This question and many more will be answered as you calculate the frequency of facial traits seen in your class! Activity #2: Genetics of Taste Brussel Sprouts… yum or yuck? Why does food taste different to different people? Be prepared to test your ability to taste, as well as form evidence based opinions to these questions!

3. Activity 1: Frequency of Facial Traits Objectives AL COS #7 Calculate frequency of facial traits. Hypothesize the method of inheritance of various facial traits. Materials Needed Student Handout: Frequency of Traits Calculator

4. What do these guys have in common? Lance ArmstrongEddy Munster

5. What do these guys have in common? Lance ArmstrongEddy Munster They both have a widow’s peak!

6. During this activity, you will calculate the frequency of the following traits in class… Tongue Roller vs. Non-Tongue Roller Widow’s Peak vs. Straight Hair Line Free Ear Lobes vs. Attached Ear Lobes Freckles Present vs. Freckles Absent Dimples Present vs. Dimples Absent Green Eyes vs. Non-Green Eyes Curly Hair vs. Straight Hair Red Hair vs. Non-Red Hair

7. Congratulations! When you have completed Activity 1, Frequency of Facial Traits, proceed to Activity 2, Genetics of Taste.

8. Activity 2: Genetics of Taste Objectives AL COS #7 Calculate class frequency of the ability to taste various chemicals. Form an evidence based opinion to answer post lab question(s). Materials Needed Student Handout: Genetics of Taste Control Taste Strip PTC Taste Strip Thiourea Taste Strip Calculator

9. Is your sense of taste determined by nature or nurture? Time to brainstorm for possible answers! After brainstorming, test your ideas through experimentation as directed by your teacher!

10. Congratulations! Since you have completed Activity 2, Genetics of Taste, you are an educated biology student qualified to pass genetics information down to others!
