The Blood Typing Game

Hour:

Directions: 1. Follow directions of class website to the `Blood Typing Game' 2. Click on the option that says `Quick Game - same patients' 3. You're task will be to determine the blood type and safely deliver a blood transfusion to 3 patients. 4. Start with the patient on the left side and you will work your way to the right. 5. Follow the directions on screen to identify the blood type of the first patient.

Patient 1:

Draw what you see when you add blood to each of the labeled vials.

Anti-A Serum

Reaction (yes or no)

Anti-B Serum

Anti-Rh Serum

*Remember: If there is a reaction, it means that marker is present in the blood*

What is Patient 1's blood type?

________________

Blood Transfusion: Now, your task is to safely perform a blood transfusion on the patient. Here are some helpful hints: Bodies will react to any markers (A,B, Rh+) that are not in their own phenotype. Rh- blood can be given to Rh+ blood types, but not vice versa O blood has no markers Fill out the data table below to keep track of your results.

Reflection Questions: Why is type O- blood considered the universal donor?

Why is Type AB blood considered the universal receiver?

Why is it important for doctors to have knowledge of blood types?

Blood Type Codominance Practice Problems

Human blood types are determined by genes that follow the CODOMINANCE pattern of inheritance. There are two equally dominant alleles (A and B) and one recessive allele (O).

1. Fill in the following chart with the missing information.

Blood Type (Phenotype)

Possible Genotype(s)

Can donate blood to:

O ("universal donor")

Can receive blood from: O

AB

AB

("universal recipient")

A

O , A

B

AB , B

2. Write the genotype for each person, based on the given description.

Homozygous for Type B Blood __________

Heterozygous for Type A Blood __________

Type O Blood __________

Type A Blood and had a parent with Type O Blood __________

Type AB Blood __________

Blood can be given to any individual __________

Heterozygous for Type B Blood __________ Homozygous for Type A Blood __________

Can only receive blood from a Type O donor __________

3. A father is heterozygous for his type B blood (BO) and the mother has type O blood. a. What are the possible blood types of the babies born from this couple?

4. A father has type AB blood and the mother has type O blood. a. What percentage of their offspring would you expect to have... Type A Blood ______% Type B Blood ______% Type AB Blood ______% Type O Blood ______%

5. A father is heterozygous for his type A blood and a mother is heterozygous for her type B blood. a. What percentage of their offspring would you expect to have...

Type A Blood ______%

Type B Blood ______%

Type AB Blood ______%

Type O Blood ______%

6. Mrs. Weasley has Type A blood but she is not sure if she is homozygous or heterozygous. Mr. Weasley is completely unsure of his blood type. Their children have the following blood types: Ron has Type O blood, Fred & George have type A blood, Ginny has type B blood and Percy has type AB blood. Show the cross to answer the following questions.

a. What is Mrs. Weasley's genotype? _________

b. What is Mr. Weasley's genotype? _________

7. In 1968, a couple accused a hospital of switching their baby with another. DNA fingerprinting did not exist at this time so the hospital traced the blood types of the family in order to determine if a mistake was made. The mother had type A blood, the father had type AB blood, and the baby had type O blood. Use the punnett square to defend your answer to the following question.

a. Did the hospital make a mistake and switch the baby? ______

8. On a recent episode of CSI, multiple people came forward claiming to be the parents of the victim. For the first set of parents, the man has type AB blood, the woman has type O blood and yet the victim has type B blood. Use the punnett square in order to determine if these people could possibly be the parents of the victim. a. Could these be the parents of the victim? _______

b. In the chart below, circle the other possible options for the parents of the victim.

Couple Bob and Gina Ted and Susan Rob and Kelly Tricia and James
