Can the parents with the blood type A and B have a child with O blood type?

Answer 1

No. They can not . Blood group antigens are expressed co dominantly that is if a person has both A antigen and B antigen he will express both. There is no way B will suppress expression A antigen. For a person to have AB blood group one of his parents should have either A or AB and the other should have either B or AB. How ever there is a remote chance of having a mutation which can express both antigens. How ever it is a very very rare situation.

Answer 2

No.

Each person receives one blood group allele (you may think of this as a code) from their mother, and one from their father, and there are three different alleles for ABO blood grouping, namely A, B and O.

While A and B are co-dominant, meaning neither one will 'defeat' each other in the actual expression of the gene, the O allele is a recessive one, meaning it will not be expressed when there is an A or B allele.

For Blood Type A, possible combinations of alleles include AA, and AO.

For Blood Type B, possible combinations include BB, and BO.

For Blood Type AB, it means that the A allele and B allele are expressed together, ie. the genotype is AB.

For type O, the only possible genotype (code) for this is OO, since the blood group O will not be expressed with the presence of a single A or B allele.

Hence two parents will Blood Type O will both have only alleles for O blood group to pass on to their offspring, and naturally their offspring will be of a Blood Type O.

Of course, if there are genetic mutations that's another story..

Answer 3

We are looking for the possible blood types of a baby.

Parental information:

• Mother type B --can be BB or BO = contributes B or O gene
• Father type B -- can be BB or BO = contributes B or O gene

Baby receives one gene from each parent:

• Baby is type BB = Type B
• Baby is type BO = Type B
• Baby is type OO = Type O

At the best, two Type B parents can only offer the B or O gene to the offspring. In order to have a Type A baby, there must be at least one A gene in the mix.

Answer 4

type of blood group AA AO BB BO AB OO

Father Blood Group B either BB or BO

Mother Blood Group B either BB or BO

So the child can be either type B or O

if it is AB, then go for a DNA testing.....................

Answer 5

Yes, parents with blood types A and B can have a child with blood type O if both parents carry a recessive O allele. This is because blood type O is recessive to both A and B.

Answer 6

Yes. The blood type of the parents has nothing to do with their sexual/reproductive compatibility. It only plays a part in determining the blood type of the child.

Answer 7

No. In the given scenario, only blood type A and O (considering that both parents are heterozygous) is possible.

Answer 8

well, with genes and blood type... it can't be true, because A+B=AB. but I'm just human.. I just can calculate and estimate it. only God knows the really truth ;)
