Question
**Genetics Problem: Blood Type Probability**

_Problem Statement:_
A man who has type O blood has a child with a woman who has type A blood. The woman’s mother has type AB blood and her father, type B. What is the probability that the child has type A blood?

- 0%
- 75%
- 100%
- 50%
- 25%

_Explanation:_
1. **Blood Type Basics:**
   - Blood type is determined by the combination of alleles inherited from the parents. 
   - Type O contains two O alleles.
   - Type A can have either AA or AO alleles.
   - Type B can have either BB or BO alleles.
   - Type AB has one A allele and one B allele.

2. **Parental Blood Types:**
   - Man (Type O): OO alleles
   - Woman (Type A, with AB mother and B father): She must have inherited one A allele from her AB mother and one B or O allele from her B father. Since she has type A blood, her genotype must be AO.

3. **Punnett Square Analysis:**
   - To determine the child's blood type probability, we need to analyze the combination of the father's OO alleles and the mother's AO alleles.
   - The possible allele combinations for the child are:
     - O from the father and A from the mother: AO (Type A blood).
     - O from the father and O from the mother: OO (Type O blood).
   - Thus, there are two possible outcomes for the child’s blood type: AO (Type A) and OO (Type O).

4. **Probability Calculation:**
   - Since the likelihood of getting AO or OO is equally probable, each outcome has a probability of 50%.

_Conclusion:_
The probability that the child has type A blood is 50%.

_Answer:_ 50%
