Read each question carefully and provide your answer in the space provided. For Punnett square questions, draw the square and indicate genotypes and phenotypes.
1. Which of the following genotypes represents blood type B heterozygous?
I^B I^B
I^B i
I^A I^B
ii
2. A person with blood type AB can receive blood from which of the following types?
Type A only
Type O only
Types A, B, AB, and O
Type AB only
3. The universal donor blood type is .
4. The inheritance of ABO blood groups is an example of both codominance and alleles.
5. A person with Rh-negative blood can only receive Rh- blood.
6. A mother has blood type A (heterozygous) and the father has blood type B (heterozygous). Draw a Punnett square to show the possible genotypes and phenotypes of their offspring. What is the probability of them having a child with blood type O?
7. If both parents have blood type AB, it is impossible for them to have a child with blood type O.
True
False
8. The Rh factor is determined by a single gene with two alleles, positive (dominant) and negative (recessive).
True
False
Match the blood type with its corresponding antigen(s) and antibody(ies).
9. Blood Type A
a. A and B antigens, no antibodies
10. Blood Type B
b. B antigens, anti-A antibodies
11. Blood Type AB
c. No antigens, anti-A and anti-B antibodies
12. Blood Type O
d. A antigens, anti-B antibodies
13. Explain how codominance is exhibited in the inheritance of ABO blood types.
