**Question:** Can you have a child with O blood type if the parents are A and B blood types?

**Explanation:**

Yes, it is possible for parents with A and B blood types to have a child with an O blood type. This occurs when both parents carry the recessive O allele. Blood type is determined by the ABO blood group system, which considers three alleles: A, B, and O. 

**Genotypes:**
- Type A blood can be AA or AO.
- Type B blood can be BB or BO.
- Type O blood is OO.

In this case, if one parent has AO genotype and the other BO, the potential genotypes for their child can be:
- AB (resulting in blood type AB)
- AO (resulting in blood type A)
- BO (resulting in blood type B)
- OO (resulting in blood type O)

Thus, the child can inherit the O allele from both parents, resulting in blood type O.
