Yes, a person with AO genotype can donate blood to a person with blood type O because type O can receive blood from A and O blood types. The A from the donor's blood will not cause a reaction with the recipient's O blood.
Yes. There are two possible genotypes for a person with type B blood: BB or BO. If a person with the BB genotype has children with a person with type O blood, then all of their children will have type B blood. But, it the person has the BO genotype, then any child they have will have a 50% chance of having type O blood.
There is only one possible blood genotype that gives group O. The person must be homozygous for type O.
The woman would have genotype AO (IAIA) for blood type A, the man would have genotype BO (IBIB) for blood type B, and their child with blood type O would have genotype OO (ii). The child inherited one O allele from each parent.
A person with blood group O is homozygous for the recessive allele: ii.
The genotype of the father is certainly OO (because blood type O is recessive). The genotype of the mother however can be AO or AA (both give blood type A). The baby will have a combination of the genes from the mother and the father (one of each) and so: - If the genotype of the mother is AA and the genotype of the father is OO, the baby will certainly have AO as genotype and has therefore blood type A. -If the genotype of the mother is AO and the genotype of the father is OO, the baby can have AO or OO as genotype. AO results in blood type A and OO in blood type O (50% chance).

The offspring blood type with parents that have O and B blood types would come out with O positive. This is taught in biology. Based on the details of the question this initial answer is incorrect. Type O is not a dominant characteristic merely a common one. A person with type B blood could have a genotype of BO or BB so there are two potential answers to this question. The parent with O type blood can only have an OO genotype. If the parents are BB and OO then all offspring will be type B phenotypically and their genotype will be BO. If the parents are BO and OO then 50% of the offspring will have the BO genotype and 50% will have the OO genotype. Phenotypes will be B and O respectively. Since the question did not include any mention of the RH factor there is no way to determine that the offspring would be positive or negative. True codominance in blood types really only shows up with the AB genotype where the phenotype of the individual matches the genotype and the person has both A and B blood factors.
Blood Type A is dominant to Blood Type O. That means that a person with genotype AA and a person with genotype AO will both have Type A Blood, while a person with genotype OO will have Type O Blood. If both parents have blood type AO, they will both have Type A Blood, but their child will have a 25% chance of having Type O blood. The blood type ratio of their children will be 25% AA (Type A Blood), 50% AO (Type A Blood), and 25% OO (Type O Blood).
I assume you are meaning in a transfusion. The ideal blood should be a perfect match. A positive should get A positive. In an emergency an A positive can receive any blood that has no B genotype. O+/-, A+/-,but NO B or AB.
A person can have type A blood with a homogenous genotype (two A alleles). In addition, you can be heterozygous A (one O and one A allele).
The baby would have blood type O positive. A child can only inherit blood type O from parents who each have at least one O allele. And since O is recessive, both parents must have two O alleles to have blood type O.
