To determine the possible blood genotypes of the father, we need to analyze the blood types involved:
- The mother's blood type is AB, which has the genotype IAIB.
- The child's blood type is A, which can have the genotypes IAIA (homozygous) or IAi (heterozygous).
Since the child has type A blood, the potential combinations of alleles from both parents must allow for this. Here's how it breaks down:
1. If the child is genotype IAi (the child got IA from the mother and i from the father), the father must carry the i allele. Therefore, the father's genotype could be:
- Type A (IAi)
- Type O (ii)
2. If the child is genotype IAIA, it would not be possible because the father would not be able to contribute an i allele, which means the father cannot be type O.
Thus, the possible genotypes for the father, based on the child being A (IAi) and the mother being AB (IAIB), would be:
- IAi (father type A)
- ii (father type O)
Therefore, the correct possible genotypes for the father are:
1. IAi (type A)
2. ii (type O)
If there are additional genotypes provided in the options, it is possible some others could be marked as correct, but based on the provided information, the primary and confirmed options are the two above.
