Pass It Down…

Course: BiologyUnit: GeneticsDeveloped by Students at Glencoe High School

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!

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

What do these guys have in common?

Lance Armstrong Eddy Munster

They both have a widow’s peak!

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 LineFree Ear Lobes vs. Attached Ear LobesFreckles Present vs. Freckles AbsentDimples Present vs. Dimples AbsentGreen Eyes vs. Non-Green EyesCurly Hair vs. Straight HairRed Hair vs. Non-Red Hair

Congratulations!

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

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

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!

Congratulations!

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