1. HAPPY FRIDAY Bellwork: Copy only the UNDERLINED WORDS and ANSWER the questions. Tongue Rolling (T) is dominant to Non-Tongue Rollers (t). 1. What are the possible GENOTYPES for the tongue-rolling trait? 2. What are the possible PHENOTYPES for the tongue-rolling trait? 3. If an individual was HOMOZYGOUS RECESSIVE for tongue-rolling, what would their PHENOTYPE look like? Their GENOTYPE? **Glue only the top portion of your HW to Page 30 of your I.A.N. to allow you to flip and the see the back as well. Title it “Punnett Square Practice”**

Their GENOTYPE? **Glue only the top portion of your HW to Page 30 of your I.A.N. to allow you to flip and the see the back as well. Title it “Punnett Square Practice”** TT, Tt, tt Tongue Rolling and Non-Tongue Rolling Phenotype = Non-Tongue Roller Genotype = tt

3. Standard : B6F - Predict possible outcomes of genetic combinations such as monohybrid crosses. Essential Question: How can I predict genetic outcomes?

4. Punnett Square practice… 1. What would be the possible outcomes for the offspring of a cross between pink flower (PP) and a white flower (pp)? P P p p Pp P = Pink p = White DAD = PP MOM = pp P = Pink p = White DAD = PP MOM = pp **When using the letters like “P and p” OR “C and c”, draw the lowercase letter in cursive or just make sure you make them look different. Otherwise, you might confuse the dominant for the recessive **

5. Phenotype: 4 Pink Flowers 0 White Flowers Genotype: 4 Pp

6. 2. Long fingers are dominant (F) to short fingers (f). Complete the Punnett square for a homozygous recessive mom and a heterozygous dominant dad. F f f f Ffff Ffff F = Long f = Short DAD = Ff MOM = ff F = Long f = Short DAD = Ff MOM = ff

7. Is the Punnett Square Correct?

8. 3. In a plant, long stems are dominant (L) to short stems (l). If a homozygous dominant flower and a homozygous recessive plant are crossed, what would be the phenotypic ratio of their offspring? L L l l Ll L = Long l = Short DAD = LL MOM = ll L = Long l = Short DAD = LL MOM = ll

9. Genotypic Ratio: 0 LL : 4 Ll : 0 ll

10. 4. Straight hair (C) is dominant to curly hair (c). What would be the probability that a child would have curly hair if both parents are heterozygous dominant? Cc C c CCCcCc CcCc cc C = Straight c = Curly DAD = Cc MOM = Cc C = Straight c = Curly DAD = Cc MOM = Cc

11. 25% chance of a child having curly hair

12. 5. Having a hitchhiker's thumb is a dominant trait (T). If a woman with a straight thumb has a child with a man who is heterozygous for the trait, what are the chances their child will have a hitchhiker's thumb? T t t t Tttt Tt tt T = Hitchhiker t = Straight DAD = Tt MOM = tt T = Hitchhiker t = Straight DAD = Tt MOM = tt

13. 50% chance of have a child with Hitchhiker’s thumb.

14. 6. What would the phenotypic and genotypic ratios be for two purple (Pp) flowers that were bred together? P p P p PP Pp pp P = Purple p = White DAD = Pp MOM = Pp P = Purple p = White DAD = Pp MOM = Pp

15. Phenotype: 3 Purple Flowers 1 White Flowers Genotype: 1 PP : 2 Pp : 1 pp

16. Human Pedigree – A Family Tree Project Essential Question: “Why do offspring resemble both of their parents?” REQUIREMENTS FOR PEDIGREE POSTER SIZE: Smallest dimensions = 11 X 17 TITLE: Family Name KEY: Trait(s) & Gender Symbols FAMILY MEMBERS: First Names CONNECTEDNESS: Lines connecting people in the family

17. EXTRA CREDIT!!! - Bring up your semester average to passing or a higher letter grade! Required: Siblings/You  Parents  Grandparents (0 points extra!) Extra Credit: Cousins/Siblings/You  Parents/Aunts/Uncles  Grandparents (10 points extra!) Extra Credit: Cousins/Siblings/You  Parents/Aunts/Uncles  Grandparents/Great Aunts/Great Uncles  Great Grandparents (20 points extra!) Going beyond Great, great grandparents will not receive further extra credit. (0 points extra!) Make a cupcake family tree, a 3D model, or a YouTube Video, etc… Let your imagination run WILD!!! (10 points extra!)

18. Over the break……. Widows Peak vs Non-Widows Peak Tongue-Rolling vs Non Tongue-Rolling Attached Ear-Lobes vs Unattached Ear-Lobes Hitchhikers Thumb vs Straight Thumb Almond Shaped-Eyes vs Round Shaped- Eyes Right-handed vs Left-handed Freckles vs No Freckles Cleft Chin vs Non-Cleft Chin Since some of you will see family members, see who has what and keep track of them. Choose ONE TRAIT from the following list that you want to follow along your family tree.

19. This activity is adaptable to everyone’s family situation. If you have any questions about how to draw a pedigree for your particular family, please see me. WARNING! Not completing the project will leave you in jeopardy of failing the 3 rd Six- Weeks/Semester.

20. Can you identify your own genotypes and phenotypes? Hairline: Widow’s peak is dominant to straight hairline Eye Shape: Almond eyes is dominant to round eyes

21. Tongue Rolling: CAN roll the tongue is dominant to cannot Eyelash Length: Long eyelashes is dominant to short eyelashes

22. Lip Thickness: Thick lips are dominant to thin lips Hitchhiker’s Thumb: Hitchhiker’s thumb is dominant to straight thumb
