Question

What would the offspring's blood type be if the mother is type 0+ (she is homozygous for Rh factor) and the father is A- (he is homozygous for type A)? Hint: You have to do two Punnett squares. The two Punnett squares must be shown to get the full points. After doing the Punnett squares, write down the possibilities of the offspring's blood type.

Answer 1

The possible blood type for the offspring would be A+.

Step-by-step explanation:

In order to determine the possible blood types of the offspring, we need to create two Punnett squares: one for the ABO blood type and one for the Rh factor. For the ABO blood type:

2. The mother's blood type is O and the father's blood type is A.
3. The mother is homozygous for O (OO) and the father is homozygous for A (AA).
4. Therefore, all the possible genotypes for the offspring will be Ao (heterozygous for A) since the A allele is dominant over the O allele.

For the Rh factor:

2. The mother is homozygous for Rh+ (++) and the father is homozygous for Rh- (--).
3. Since the father is Rh- and does not have the Rh antigen, all the offspring will be heterozygous for the Rh factor (Rh+/-) since the Rh+ allele is dominant over the Rh- allele.

Therefore, the possible blood type for the offspring will be A+.
