alleryABO blood groups: an individual with genotype I^A i has blood type:
AA (I_A dominant over i)
BO
CB
DAB
Answer & Solution
Correct answer: A. A (I_A dominant over i)
I_A and I_B are both dominant over i.
**Genotypes:** I_A I_A or I_A i = A
I_B I_B or I_B i = B
I_A I_B = AB; ii = O. So I_A i → A blood type.
