Blood Typing Catalyst: In Higgins Hurricane mascots, the gene for color is co-dominant. Hurricanes can be blue (BB), yellow (YY), or blue and yellow (BY). Create a Punnett square to show the potential offspring of a blue hurricane and a red hurricane. List the genotype AND phenotype percentages. Write in complete sentences! Dont talk during the Catalyst! LS 30: Explain the role of ATP in the cell LS 29: Analyze photosynthesis and cellular respiration LS 9: Compare mitosis and meiosis LY 3: Identify and order the stages of mitosis Unit 2 Mastery Overall Mastery for All Units Have you ever wondered Why do we have different types of blood? Why could you die if you get a transfusion of the wrong type of blood? How can parents give birth to kids who have a different blood type than them? Objectives By the end of today, SWBAT Create and analyze Punnett squares for blood typing Remember INcomplete dominance is where the heterozygous genotype is IN BETWEEN both the dominant and the recessive genotype. RR red Rr pink Rr white Remember CO-dominance is where the heterozygous genotype shows both dominant and recessive equally. (They CO-operate.) RR red RW spots WW white Homework Review Quiz! Put away your binders Turn your desks into rows And lets ace that quiz! You have 15 minutes Blood Typing Sometimes there are more than two alleles for a trait. The most important one for you to learn about is blood type! Key Point #1: Blood type has three alleles: I A, I B, and i. I A and I B are co-dominant. i is recessive. Blood Types I A and I B are co-dominant I A I A = Type A I B I B = Type B I A I B = Type AB i is recessive I A i = Type A I B i = Type B i i = Type O Blood Typing Show the potential offspring between a mother who is heterozygous for Type A blood and a father who is heterozygous for Type B blood. IBiIBi I A i IAIBIAIB GENOTYPES: PHENOTYPES: I A i: 25% I B i: 25% I A I B : 25% ii: 25% Type A: 25% Type B: 25% I B i I A ii Type AB: 25% Type O: 25% GP 1 Show the potential offspring between a father who is homozygous for Type A blood and a mother who is homozygous for Type B blood. GENOTYPES: PHENOTYPES: GP 2 Show the potential offspring between a mother who is Type O blood and a father who is Type AB blood. GENOTYPES: PHENOTYPES: GP 3 Show the potential offspring between a mother who is Type AB blood and a father who is heterozygous for Type B blood. GENOTYPES: PHENOTYPES: GP 4 Show the potential offspring between a mother who is heterozygous for Type A blood and a father who is heterozygous for Type B blood. GENOTYPES: PHENOTYPES: Project Work Time Exit Question Rhianna has heterozygous Type B blood, and Drake has Type AB blood. Create a Punnett Square to show their potential offspring. List the genotype AND phenotype percentages. Write in complete sentences! Dont talk during the Exit Question!
