Question

3 a man who is homozygous for type a blood marries a woman who is heterozygous for type a blood. can they have a child with type o blood? show your punnett square to prove your answer.

Explanation:

Step1: Determine the genotypes

The man is homozygous for type A blood, so his genotype is \(I^{A}I^{A}\). The woman is heterozygous for type A blood, so her genotype is \(I^{A}i\).

Step2: Set up the Punnett square

	\(I^{A}\)	\(I^{A}\)
\(i\)	\(I^{A}i\)	\(I^{A}i\)

Step3: Analyze the offspring genotypes

The possible genotypes of the offspring are \(I^{A}I^{A}\) (type A) and \(I^{A}i\) (type A). There is no \(ii\) (type O) genotype.

Answer:

No, they cannot have a child with type O blood.
