Question
What is the genotype of a person with type A blood who had a father with type O blood?
- AB
- AO
- AA
- OO
Hint:
AO
The correct answer is: AO
The genotype of a person with type A blood will have AO, when his father has O type of blood.
If the father is heterozygous, there is a 50% probability for a blood type A child and a 50% probability for a blood type O child. If the father is homozygous, every offspring will be blood type A.
