A parent with type O blood marries a AB what would be their phenotypes?

Possible Phenotypes of the Offspring:

Based on the given information that one parent has type O blood (genotype OO) and the other parent has type AB blood (genotype AB), their offspring can have the following phenotypes:

1. Type A blood (genotype AO):

- Inherits the A allele from the AB parent and the O allele from the O parent.

2. Type B blood (genotype BO):

- Inherits the B allele from the AB parent and the O allele from the O parent.

3. Type AB blood (genotype AB):

- Inherits the A allele from the AB parent and the B allele from the AB parent.

4. Type O blood (genotype OO):

- Inherits the O allele from both the AB parent (who is heterozygous) and the O parent.
