There is equal chance (one in two) that each of their children will have either type A or type B.
The A and B antigen alleles are both dominant to the defective antigen allele (O). The parent with AB can donate either an A or a B to the offspring; the O parent can donate only an O so the only possible combinations are AO and BO. Because O is recessive to A and B, the child will have either A or B type blood.
O type blood (ii) and AB type Blood (IAIB) 50% of their chldren will have type A blood (IAi) and 50% will have type B blood (IBi)
If the child is typo O, and the mother is type A, her genotype must be AO, and the father, if type B, must have a genotype of BO.
AO + BO has a 25% change of making an O baby.
Type A or type B. For more information see the related link below.
2 IAi : 2 IBi
A or B. Can't be AB, can't be O.
The mother is AO and the father is BO.
The woman could be AA or AO and the man could be BB or BO. The children would all be AB.
if a man were non- hemophiliac and he marries a woman whois homozygus for nan-hemophilia,give the possible genotypes of the children
Assuming the dystonia is hereditary and is a recessive gene which will be called "d" for simplicity, that means the man must be "dd" and the woman is "Dd". This is the only way they could have a child who is "dd" like the father, but not the mother.

Marriage has nothing do to with genotypes. Marriage, a blow to the head, oranges, and playing golf are all the same in that they don't affect genotypes in any way.Now...perhaps you meant to ask about the offspring of a man and a woman with such genotypes. Traditionally marriage precedes the birth of a child, but not always, so call it what it is: sex. So the question is if a man (genotype AS) has sex with a woman (genotype AS), will the baby be at risk for sickle cell anemia. There is a 25% chance that the child will have the disease (genotype SS).Again, to drive the point home, the proper wording of this question should not include "can" even if we get rid of the marriage nonsense. Ability here is not an issue. We also can't answer if they should have a baby, because that is entirely their decision even if they know the risks.
The woman could be AA or AO and the man could be BB or BO. The children would all be AB.

All blood groups are possible for children born from a combination such as this, regardless of which group is the male and which is the female.
There are three alleles for blood type which can be represented by IA, IB, and i. A person with blood type O has the genotype ii. A person with blood type AB has genotype IAIB. If these two people produce children, those children will inherit one allele from each parent. They will therefore certainly inherit the i allele from their mother and either the IA or the IB from their father. The children with the genotype IAi will have type A blood, since the IA allele is dominant to the i allele. The children with the genotype IBi will have type B blood, since the IB allele is also dominant to the i allele.

This is possible if the man is heterozygous for blood type A (Ai, not AA). Each parent passes down one allele to a child. So, if the woman is type O (ii) and the man is heterozygous for A (Ai), the child receives i from the mom and A or i from the dad. Consequently, the children can be either type O (ii) or A (Ai).
Depending on their actual genotypes and which of those genes the offspring receive, their offspring might have AB, A, B, or O blood type. For the man to have a phenotype blood type A he might have either genotype AA or Ao. For the woman to have a phenotype blood type B she might have either genotype BB or Bo.
Yes it is possible. The child can have A, B and O blood group.
No
YES! If the woman has type AB blood type andthe man has type BO blood tye it is possible for them to have a child with AO blood type which registers as type A. It is rare though. Genetics tell us that they have a 50% chance of a baby with type B blood and a 25% chance of a baby with type AB blood. That means that they have a 25% chance of having a baby with type A blood. Remember this doesnt account for positive or negaive antibodies.
