Question restatement: If a mother's blood type is A and the father's blood type is O, their offspring's blood type will be:

Options:
- type O
- type A
- type B or type O
- type A or type O

Option 1: 'type O'
This answer is incomplete. While a child from an A × O cross can indeed be type O, it is not limited to O; the child can also be type A if the mother contributes an A allele and the father contributes an O allele, resulting in AO genotype. Therefore, 'type O' alone is not always correct.

Option 2: 'type A'
This option overlooks another possible outcome. If the mother provides the A allele and the father provides the O allele, the resulting AO genotype yields type A blood. However, there is also the possibility of OO genotype (type O) when the A allele is not present in the offspring. So claiming only type A is incorrect.

Option 3: 'type B or type O'
This is inaccurate. Type B cannot arise from an A × O cross because neither parent contributes a B allele. The B phenotype would require a B allele from one or both parents, which is not present here.

Option 4: 'type A or type O'
This is the correct consequence of an A (genotype could be AO or AA) × O (genotype OO) cross. The offspring can inherit an A allele from the mother and an O from the father, giving type A, or inherit O from the mother (if the mother contributes the O allele in some scenario) and O from the father, giving type O. In standard genetics, A × O yields either type A (AO) or type O (OO); type B or AB is not possible.

Summary: Through Mendelian inheritance, A can pair with O to produce AO (type A) or OO (type O). The other options fail because they either ignore a possible outcome (type A or type O) or allelic possibilities, or they incorrectly include type B which cannot arise from A × O cross.
