Tues., 9/9
Topic: Blood Type
Homework: Study for test Thurs./Fri.
& If you were absent yesterday, finish Class Traits Lab (pg. 34)
Get out
Calendar
Pencil & comp book
Glue/tape/stapler
(Maybe) Colors (for later)
If you were absent
You missed the Punnett Square Quiz. You can do it today after school, or you can miss some of Review on Wed.
We finished pg. 34. You need to finish on your own.
To Do
1. One handout on Pick Up Table.
2. Set up pg. 39 for Cornell notes. Title: Blood Types.

2. Blood Transfusions
History of Blood Transfusion from

5. Genetics of Blood
Your blood type is decided by genes inherited from your parents.
The human blood types are type A, type B, type O, and type AB.

6. Genotypes & Phenotypes
3 alleles or genes for blood type: A, B, & O.
6 possible genotypes: AA, AO, BB, BO, AB, and OO.

7. Dominant & Recessive
O is recessive
A is dominant
B is dominant

8. B O A B A O A O B O O O Example:
Dad has Type B blood type (phenotype) because he has a B gene (blue) and an O gene (yellow) genotype. B O A B A O A
Mom has Type A blood because she has an A gene (red) and an O gene (yellow) O B O O O

9. B O A O A A B O B O O O Example: Type A phenotype Type B phenotype
Dad has Type B blood type (phenotype) because he has a B gene (blue) and an O gene (yellow) genotype. B O A O A A B ?
Type A phenotype
Mom has Type A blood because she has an A gene (red) and an O gene (yellow) O B O O O
Type B phenotype
Type O phenotype

10. A B A B Co-dominant Two alleles are both dominant & show up together.
Not type A blood,
Not type B blood…
You get Type AB blood!

11. You Try:
Dad has Type AB blood (phenotype) because he has an A gene (red) and a B gene (blue) genotype B A A
Mom has Type A blood (phenotype) because she has an A gene (red) and an O gene (yellow) O

12. B A A A A B A B O A O O You Try: Type AB phenotype Type B phenotype
Dad has Type AB blood (phenotype) because he has an A gene (red) and a B gene (blue) genotype B A A A A B A
Mom has Type A blood (phenotype) because she has an A gene (red) and an O gene (yellow)
Type AB phenotype
Type A phenotype B O A O O
Type A phenotype
Type B phenotype

13. Blood Phenotypes & Genotypes
Type A blood AO AA
Type B blood BO BB
Type O blood OO
Type AB blood AB
