Question

A man with type a blood marries a woman with type ab blood. according to predicted outcomes based on genetics, their children may have all blood types except type

Answer 1

The only blood type the children might not have would be O. They could have A, B, or AB.

Answer 2

The correct answer would be blood group O.

The blood group of a father is A. So, his genotype would be
`I^(A)`_ (
`I^(A)I^(A)` or
`I^(A)i`).

The blood group of a mother is AB. So, her genotype would be
`I^(A)I^(B)`.

The cross would result in the production of offspring with all types of blood groups (A, B, and AB) except O as O is the recessive trait and require homozygous recessive condition (
`ii`).
