Answer:

Olga has blood group type A with genotype IAi (heterozygous)

Step-by-step explanation:

First Marriage:

  • 1st Husband-Type A (IAi) x Olga- Type A (IAi) = Child-Type O (ii)

Second Marriage:

  • 2nd Husband-Type B (IBIB) x Olga- Type A (IAi) = Child-Type AB (IAIB)

Olga genotype is heterozygous (IAi) this is why her children are having different blood group types.
