1. 5 HAPPY MONDAY Bellwork: Turn in Pages 74 (to tray) & 80 (to front table). Draw the pedigree chart and determine the genotypes for numbers 1-5 using the information given. Shaded = Tongue Rolling Not Shaded = Non Tongue Rolling Tongue Rolling (T) is Dominant to Non Tongue Rolling (t) Tttt Tttt Small Group CHAMPS E2 Computer

2. With your table partner, write down the correct answers for questions on your bellwork page. The pedigree chart below depicts albinism, a recessive trait, in a family. Use the pedigree chart to answer questions. A. How many affected females are shown? A.1 B.2 C.3 D.4 B. What is the mostly likely genotype(s) of individual #1? A.AA or Aa B.Aa only C.aa only D.AA, Aa, or aa 1 aa Aa AA or Aa

3. Aa Case Study #1 A = Normal a = albinism Aa aa A- -2 points each shape -2 points each genotype

4. Case Study #2 H = Huntington's Disease h = Normal hh Hh H- -2 points each shape -2 points each genotype

5. Case Study #3 N = Neurofibromatosis n = Normal Nn N- nn 1.Heterozygous 2.Nn 3.No -2 points each genotype -2 points each

9. Dihybrid Cross: a cross that shows the possible offspring for two traits Fur Color: B: Black b: White Coat Texture: R: Rough r: Smooth In this example, we will cross a heterozygous individual with another heterozygous individual. Their genotypes will be: BbRr x BbRr

10. Dihybrid Cross BbRr x BbRr Step 1: Find ALL possible gametes that can be made from each parent. Remember, each gamete must have one B and one R. DADMOM

11. Dihybrid Cross BbRr x BbRr Possible gametes: BR Br bR br DADMOM Step 2: Arrange all possible gametes for one parent on the top of your Punnett Square and the other parent on the side F O I L

12. Dihybrid Crosses: a cross that shows the possible offspring for two traits Fur Color: B: Black b: White Coat Texture: R: Rough r: Smooth BbRr x BbRr BR bR br bR Br BR br Br Step 3: Fill in the Punnett Square (find the possible genotypes of the offspring)

16. Practice in your notes… In pea plants, yellow seeds (Y) are dominant over green seeds (y), and rounded peas (R) are dominant over wrinkled peas (r). Cross (what do you have to draw?) a plant that is heterozygous for both traits with a plant that is homozygous recessive for both traits. Draw a Punnett square to show all possible offspring, and determine the genotypic and phenotypic ratios. Identify Y y R r Assign yellow green rounded wrinkled Match Male = YyRrFemale = yyrr
