A mother has blood group A, the father has blood group AB, and their child has blood group A. What can be the possibility of genotypes of all three, respectively? A. I^A I^A | I^A I^B | I^A I^A B. I^A i | I^A I^B | I^A i C. I^A I^A | I^A I^B | I^A i D. I^A i | I^B i | I^A i E. I^A i | I^A I^B | I^B i Choose the correct answer from the options given below:

Step-by-step solution

The blood group of the mother is A, so her genotype can be I^A I^A or I^A i . The blood group of the father is AB, so his genotype must be I^A I^B . The blood group of the child is A, so the child's genotype can be I^A I^A or I^A i . Evaluating the given statements: A. I^A I^A | I^A I^B | I^A I^A : The child inherits I^A from the mother and I^A from the father. This is possible. B. I^A i | I^A I^B | I^A i : The child inherits i from the mother and I^A from the father. This is possible. C. I^A I^A | I^A I^B | I^A i
