What possible phenotypes can result from a man with genotype AO and a woman with genotype AB?

In this scenario, we are looking at the potential phenotypes of offspring from a man with genotype AO and a woman with genotype AB.

To determine the possible phenotypes, we first need to understand what each genotype represents in terms of blood types. The genotype AO indicates that the man can pass on either the A allele or the O allele. The woman, with the AB genotype, has one A allele and one B allele that she can pass on.

By combining these alleles in a Punnett square:

1. If the man contributes the A allele and the woman contributes the A allele, the outcome is genotype AA, which corresponds to blood type A.

2. If the man contributes the A allele and the woman contributes the B allele, the outcome is genotype AB, which corresponds to blood type AB.

3. If the man contributes the O allele and the woman contributes the A allele, the outcome is genotype OA, which is also blood type A.

4. If the man contributes the O allele and the woman contributes the B allele, the outcome is genotype OB, which corresponds to blood type B.

Thus, the possible blood types from this combination of parental genotypes can be A (from alleles AA or AO), B (from alle
