Presentation Transcript

  1. Blood Typing • Beyonce’s blood is IAIB, and has Rh factor. • What type blood does she have? • Can she receive Type A Rh- blood? • Can she receive Type B Rh+ blood? • Can she give blood to someone who is Type AB Rh-? Write in complete sentences! Don’t talk during the Catalyst!

  2. Have you ever wondered… • How parents can give birth to kids who have a different blood type than them?

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

  4. Agenda • Catalyst/Homework Review • Quiz • Blood Type Punnett Squares • MAURY POVICH!!! • Independent work time • Exit Question

  5. Catalyst/Homework Review

  6. Quiz! • Put away your binders… • Turn your desks into rows… • And let’s ace that quiz! You have 20 minutes

  7. Remember… • IA and IB are co-dominant • IA IA = Type A • IB IB = Type B • IA IB = Type AB • i is recessive • IA i = Type A • IB i = Type B • i i = Type O

  8. Teacher Models 1 • Show the potential offspring between a mother who has Type AB blood and a father who has Type O blood. GENOTYPES: PHENOTYPES:

  9. Teacher Models 2 • 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:

  10. 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:

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

  12. 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:

  13. Why We Care… • Today, we can use paternity tests to analyze a man’s DNA. If it matches the DNA of a child, this proves that they are father and son. • But it wasn’t always this way. • Back in the day, scientists used BLOOD TYPES and PUNNETT SQUARES to figure out…

  14. WHO DAT BABY DADDY?

  15. Scenario 1 • Katie is heterozygous for Type A blood (IAi). Her baby is type O (ii). She is not sure if Richard, her husband, or Adam, her husband’s best friend, is the father… • Richard has type AB blood (IA IB ) • Adam has type B blood (IBi)

  16. Katie’s baby is type O (ii). Who is the father?!?!?! Adam Richard IB i IA IB IAIB IAi IAIA IAIB IA IA Katie IBi ii IAi IBi i i

  17. Scenario 2 • Samantha has type AB blood and so does her baby. She is not sure whether Nick or Ron is the father of her baby…. • Nick has type O blood • Ron has type B blood • Who dat baby daddy is? Use Punnett Squares to prove it.

  18. Samantha has type AB blood and so does her baby. Nick i i Nick could not have a child with Samantha who has AB blood!!!!! IAi IAi IA IA Sam IBi IBi IB

  19. Scenario 3 • Nesha is homozygous for Type B blood. Her baby is heterozygous for Type B blood. She is not sure if Thomas, her personal trainer, or Jonny, her brother-in-law, is the father… • Thomas has Type AB blood • Jonny is heterozygous for Type A blood

  20. Nesha’s baby is heterozygous for Type B blood. Who is the father?!?!?! Thomas Jonny IA IB IA i IAIB IBIB IAIB IBi IB IB Nesha IAIB IBIB IAIB IBi IB IB

  21. Scenario 4 • Jackson is heterozygous for Type B blood, and his mother has Type AB blood. His father has Type AB blood, also. • What does this mean?! (Prove your answer with a Punnett Square!)

  22. JACKSON IS ADOPTED (OH SNAP!!!)

  23. Scenario 5 • Lizzeh has Type O blood, and her mother is heterozygous for Type A blood. She isn’t sure who her father is. • Terrance, her mother’s pool boy, is heterozygous for Type A blood. • Simon, her grocery clerk at Rouse’s, is heterozygous for Type B blood.

  24. MAURY CAN’T FIGURE THIS ONE OUT!!!  Lizzeh has Type O blood, and her mother is heterozygous for Type A Terrance Simon IA i IB i IAIA IAi IAIB IAi IA IA Mother IAi ii IBi ii i i

  25. Independent Practice • Work on the extra credit assignment or homework

  26. 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!
