1. HAPPY WEDNESDAY 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?

3. 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 **

4. 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

5. 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

6. 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

7. 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

8. 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

9. Do you want to build a foldable? =-) Grab 5 sheets of colored paper and arrange them like this…

10. And then… Fold them in half like this…. *note that some rearranging may need to take place before you COMMIT to the fold

11. Next…. COMMIT to the fold! It should look like this…
