Answer:
C. 100 percent
Explanation:
The woman is heterozygote: AO, while the man is homozygote: BB
By crossing the two:
AO x BB
A+B, A+B, O+B, O+B
AB, AB, OB, OB
We have two AB and two OB offspring. Both AB and OB are heterozygotes.
Thus all their offspring will be heterozygous.
<em>Had the question asked what proportion will be OB, the answer would have been 50%.</em>
Since the question asked, what proportion will be heterozygotes and not about the specific genotype, the correct answer is C. 100 percent
