Yes. Someone is type A if their alleles are either Ia and Ia OR Ia and Io. Having either combination will yield someone's blood group as type a. Suppose both parents have the latter combination Ia and Io. Using a punnett square, there is a twenty five percent chance that the child will get Io and Io (type O blood).

Is it possible for parents who are both blood group O to have babies who are blood group A?

If one parent has blood type B and the other blood type O, it is possible to have a baby of blood type O or B. It is NOT possible (0% chance) to have a baby with blood type A.

A + ; A - ; Ab + ; Ab -; O- ; Any ONE parent may carry these, taking into account the possible masks of the target group


For a child to have A blood type do both parents have to be A?

no, if both parents are A still there is a chance of O baby ,but for the child to have A blood type atleast one of the parents must have A or AB blood group Parents having the following blod groups may have an A baby AA and AA baby will have A blood group only AA and AO baby with A group only AO and AO baby may have A or O blood group AB and OO baby with A or B blood group AA and OO baby with A blood group only AAand AB baby with A or AB blood group AO and BO baby of A AB B or O blood group AO and AB baby of A AB or B blood group AB and AB baby having A B or AB blood group (each individual has one,two or no antigens .when no antigen it results in O blood group ,when one or two A antigens ,the person has A blood group so its not necessary that both parents of A blood group child have A blood type

AB and O parents what will be the effect on child?

When the parents are with blood group AB and O, the possible blood group of the child would be either A or B. This is because the blood group AB has the genotype AB and blood group O has the genotype OO. Thus upon recombination, the only outcomes would be AO - meaning blood group A, or BO- meaning blood group B.


Is it possible for a child with O negative blood group to have both parents with O positive blood groups?

Yes. Negative is recessive.


Is there a possibility to have blood type A of the baby if parents are both blood type o?

No, it is not possible for the baby to have an A group with both parents being O. This is because the parents would have the genotype OO,thus on recombination, the only possible outcome is again an O.

Is it possible for a baby to have a different blood type then the parents?

It is possible if your parents have different blood types. Example, if your father is A with a recessive O, and mother is B with a recessive O, you could easily land up with a O blood group. However, an AB father can have only an A, B or AB child depending on the mothers blood group, but surely NOT 'O.'
