Question

A man with blood group AB marries a woman with blood group O. What is the probability that their child will have blood group A?

• A. \( 0\% \)
• B. \( 25\% \)
• C. \( 50\% \)
• D. \( 75\% \)

Hint:

When solving blood group inheritance problems, use a Punnett square to determine the possible genotypes. Remember that the \( i \) allele is recessive, so blood group O only appears when the genotype is \( ii \).
