To determine the possible blood types of the children from a father who is heterozygous for type A blood and a mother who is homozygous for type B blood, we first need to define the genotypes involved:
- Father (heterozygous for type A blood): His genotype can be represented as \( I^A i \), where \( I^A \) is the allele for type A blood and \( i \) is the allele for type O blood (since A is dominant over O).
- Mother (homozygous for type B blood): Her genotype is \( I^B I^B \), where \( I^B \) is the allele for type B blood.
Now, we can create a Punnett Square to determine the possible genotypes of their children.
\[ \begin{array}{c|c|c} & I^B & I^B \ \hline I^A & I^A I^B & I^A I^B \ \hline i & I^B i & I^B i \ \end{array} \]
Possible Genotypes:
From the Punnett Square, we can see the following potential genotypes for the children:
- \( I^A I^B \) (Type AB blood)
- \( I^B i \) (Type B blood)
Possible Blood Types:
So the possible blood types of the children would be:
- Type AB
- Type B
There are no possibilities for type A or type O blood in this scenario.
