1. 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! Don’t talk during the Catalyst!

8. 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?

9. Objectives By the end of today, SWBAT…  Create and analyze Punnett squares for blood typing

10. Remember  INcomplete dominance is where the heterozygous genotype is IN BETWEEN both the dominant and the recessive genotype.  RR – red  Rr – pink  Rr – white

11. Remember  CO-dominance is where the heterozygous genotype shows both dominant and recessive equally. (They CO-operate.)  RR – red  RW – spots  WW – white

12. Homework Review

13. Quiz!  Put away your binders…  Turn your desks into rows… And let’s ace that quiz! You have 15 minutes

14. 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.

15. 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

16. 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%

17. 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:

18. GP 2  Show the potential offspring between a mother who is Type O blood and a father who is Type AB blood. GENOTYPES: PHENOTYPES:

19. 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:

20. 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:

21. Project Work Time

22. 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! Don’t talk during the Exit Question!
