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.
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
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.

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.
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.
