Read each question carefully and provide your best answer. This worksheet covers the principles of blood type inheritance and related concepts.
1. Which of the following genotypes represents blood type A?
I^A i
I^B I^B
ii
I^A I^B
2. A person with O- blood type is considered a universal donor because:
They have both A and B antigens.
They have no A, B, or Rh antigens.
They have Rh antigens but no A or B.
They have A and B antibodies.
3. The presence or absence of the Rh factor determines whether a blood type is positive or .
4. If a person has the genotype I^A I^B, their phenotype is blood type .
5. A person with blood type AB is considered the universal because they have no A or B antibodies in their plasma.
6. Explain the concept of codominance as it applies to ABO blood types.
7. Describe hemolytic disease of the newborn (HDN) and how Rh incompatibility plays a role.
8. A person with blood type B can safely receive blood from a donor with blood type A.
True
False
9. Antigens are proteins found on the surface of red blood cells.
True
False
10. A mother has blood type A (heterozygous) and a father has blood type B (heterozygous). What are the possible blood types and their probabilities for their offspring? Show your work using a Punnett square.
