One parent would need to have:
type AO, AA, or AB
and
rh ++ or +-
and the other parent would need to have:
type BO, BB, or AB
and
rh ++ or +-
A person with AO or AA will have type A blood; a person with ++ or +- will have + as the rh factor; a person with BO or BB will have type B blood.
In other words neither can be O. And BOTH cannot be A or B or negative. As long as one carries A (by either being A or AB) and one carries B (by being either B or AB) a child can have AB blood. Negative is recessive therefore as long as one parent has positive blood it is fine. :)
What else can I help you with?
Can o positive blood group and o positive blood group parents have child?
Yes, blood type has no bearing on weather or not the parents can have a child
Can parents with o blood group and a blood group produce a- Blood group child?
Yes, parents with O and A blood types can have a child with A- blood type. The child would inherit one A allele from the parent with A blood type and one negative Rh factor from the parent with O blood type.
How can two parents with blood type O negative have a child with blood type AB?
It is not possible for two parents with blood type O negative to have a child with blood type AB. In the ABO blood group system, type O is recessive and AB is a combination of A and B, making it impossible for two parents with type O blood to produce a child with type AB blood.
Blood group can two A people have a child who is O?
Yes this could happen if the geno-type of both parents is heterozygous, what i mean by that is to have this symbol for both parents : IAi X IAi so to have a child with type O, the possibility for that is 25%
Can O positive blood group and B positive blood group parents have child?
Yes, it is possible for parents with O positive and B positive blood groups to have a child with either O positive or B positive blood group, as each parent can pass on either their O or B allele to their offspring.
Can o positive blood group and o positive blood group parents have child?
Yes, blood type has no bearing on weather or not the parents can have a child
Can both parents with blood group B have a child with blood group O?
Type your answer here... yes
Can parents with o blood group and a blood group produce a- Blood group child?
Yes, parents with O and A blood types can have a child with A- blood type. The child would inherit one A allele from the parent with A blood type and one negative Rh factor from the parent with O blood type.
If husband is type ab and the wife is type a can they have a child with type o blood?
Simple answer - NO. The child will always have the same blood group as one of its parents.
If a child does not have either one of his parents blood type is he there child?
yes. If one parent has blood group A (as in genotype AO) and the other has blood group B (as in genotype BO) can have a child with blood group O
If a father and mother of a child are o positive what blood group would the child be?
The child has to get his/her blood type from the parents. So therefore if both parents are O type then the kid has to be O type. This makes sense to me.
What will be the blood group of a child if the parents were bb?
If both parents are genotype BB, the child can only be blood type B. The child's genotype would also be BB.
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
Can parents both blood type O have a child with A negative blood?
No, At least one parent would have to be an A (or an AB) for a child to have group A blood.
Can O and A blood group parents have child?
Yes,but if the baby is blood type B then there is ABO incompatibility.
How does a A blood type mother AND a father have a -0 blood type child?
The mother and father both have heterozygous alleles for the blood group A. The blood group A can have the alleles AA or AO, when both parents are AO, there is a one in four chance that the child will have blood group O as this blood group is recessive.
How can two parents with blood type O negative have a child with blood type AB?
It is not possible for two parents with blood type O negative to have a child with blood type AB. In the ABO blood group system, type O is recessive and AB is a combination of A and B, making it impossible for two parents with type O blood to produce a child with type AB blood.
