A woman is searching for her father and she has type O blood. She looks through records of men who could be her father. Which blood type can she eliminate from her search? (In other words, her dad CANNOT be what blood type.) Explain how you know this.

Step-by-step explanation:
Explanation:
The woman is blood type A, but we know her genotype must be Ao (not AA) because she has a daughter with blood type O. That means the daughter got an o allele from each parent.
That's why dad must have at least one o. He could have three possible blood types (O, A, or B) with one genotype for each (oo, Ao, or Bo). The father cannot be blood type AB because then he couldn't give his daughter an o allele.
If the father had an Ao genotype, the cross below shows the possible children. You can see the couple would have a 25% chance of having a child with blood type O.

Answer:
In blood typing, three alleles A, B, and O are usually expressed. Alleles A and B are both dominant, while O is recessive. Hence, if her mother's blood type is B, and the father's blood type is O, then their child must be either B or O.
