We are looking for the possible blood types of the PARENTS.
Available information:
- Baby type A -- can be either AA or AO
- At least one parent must be type A.
- Mama type AA/AO + Papa AA/AO = Baby type AA, AO, OO
- Mama type AA/AO + Papa BO = Baby type AB, AO, BO, OO
- Mama type AA/AO + Papa AB = Baby type AA, AO, BB, BO, AB
- Mama type AA/AO + Papa OO = Baby type AO, OO
Other than that, as long as Papa contributes an A or an O, the baby will be Type A.

You know it's AO because if it were AB the person would be type AB since A and B are codominant. O is recessive to both. So....If you crossed an AO with an AO you would have a 75% chance of having type A and a 25% chance of type O.

∙ 10y agoThe parent with Type A blood could be genotype AA or AO.
The parent with Type B blood could be genotype BB or BO
Children from this pairing would be genotype AB, AO, BO, OO.

What is the genotype of a woman with A blood and a man with b blood and a child with o blood?
In this case both parents must be heterozygous to have this child. This means the mother will have the genotype AO and the father will have the genotype BO. In order to have blood type O, the child must have the genotype OO.
Christine has type b blood and her father has type O blood whit is Christines genotype?
The genotype is either BB or BO. The antigens on the blood cell are B and the antibodies in the blood plasma are A.
What blood type would a baby have if both parents have blood type O positive?
The gene for blood type O is recessive. The mother can only have the phenotype O if she has the genotype OO. The gene for blood type B is dominant, the father has the phenotype B, but can have the genotype BB or BO. If the father is genotype BB, the child will be B + O = BO genotype; hence B phenotype. If the father is genotype BO, the child can be B + O = BO genotype; hence B phenotype (50% chance). Or O + O = OO genotype (O phenotype, 50% chance). * Phenotype = displayed trait that can be found with a simple blood test. * Genotype = genetic make up (one part from each parent), this requires a DNA test to be confirmed; however, it can sometimes be deduced by logic.
What are the genotypes of the male parent blood type B mother type 0 and female parent blood type A father type B?
The parents have the following genotypes:Type B = genotype BB or BOType O = genotype OOType A = genotype AA or BOFor the appropriate crosses: BB/BO x OO = Baby Type BO or OOAA/AO x BB/BO = Baby Type AB, AO, OO
Determine the possible genotypes and phenotypes with respect to blood type for a couple whose blood types homozygous A and heterozygous B?
Parents: AA (type A) and Bo (type B) Children would be AB (type AB) and Ao (type A).
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.
What is the genotype of a woman with A blood and a man with b blood and a child with o blood?
In this case both parents must be heterozygous to have this child. This means the mother will have the genotype AO and the father will have the genotype BO. In order to have blood type O, the child must have the genotype OO.
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
What are the phenotypes and genotypes of the offspring from the mating of a person with type B blood with a person with type O blood in codominance?
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.
Baby Y has parents with AB and A blood types have a daughter with type A blood, what is baby Y’s genotype?
The blood type A is determined by having either two A alleles (genotype AA) or one A and one O allele (genotype AO). In this case, since the parents have blood types AB and A, they can only pass on an A allele or a B allele to their child. If the parents have a daughter with blood type A, it means they both contributed an A allele, as the daughter cannot have a B allele since her blood type is A. So, the genotype of the daughter is AO. Now, if we consider Baby Y, we can infer that Baby Y could inherit one A allele from one parent (let's say from the parent with blood type A) and one A allele or one B allele from the other parent (the parent with blood type AB). Therefore, Baby Y's genotype could be either AA or AB.
If the mother blood type is B and father A and the child B what is the cross Genotype of both parents?
If the child is type B, then the father cannot be genotype AA, and must be type AO. Thus, the child cannot be type BB, but must be type BO. The mother can be type BB or BO.
Christine has type b blood and her father has type O blood whit is Christines genotype?
The genotype is either BB or BO. The antigens on the blood cell are B and the antibodies in the blood plasma are A.
Is it possible for two parents with type B blood to have with type O blood?
I assume the question is "Is it possible for two parents with type B blood to have a child with type O blood?" Yes they can, if both parents have BO genotype. The chance of the child having O blood is 25% in this case. Source: http://en.wikipedia.org/wiki/Blood_type
What blood type would a baby have if both parents have blood type O positive?
The gene for blood type O is recessive. The mother can only have the phenotype O if she has the genotype OO. The gene for blood type B is dominant, the father has the phenotype B, but can have the genotype BB or BO. If the father is genotype BB, the child will be B + O = BO genotype; hence B phenotype. If the father is genotype BO, the child can be B + O = BO genotype; hence B phenotype (50% chance). Or O + O = OO genotype (O phenotype, 50% chance). * Phenotype = displayed trait that can be found with a simple blood test. * Genotype = genetic make up (one part from each parent), this requires a DNA test to be confirmed; however, it can sometimes be deduced by logic.
What are the genotypes of the male parent blood type B mother type 0 and female parent blood type A father type B?
The parents have the following genotypes:Type B = genotype BB or BOType O = genotype OOType A = genotype AA or BOFor the appropriate crosses: BB/BO x OO = Baby Type BO or OOAA/AO x BB/BO = Baby Type AB, AO, OO
What genotypes give you A B ABand O blood type?
The possible genotypes of blood type A are AA and AO. The possible genotypes of blood type B are BB and BO. The genotype of blood type AB is AB. The genotype of blood type O is OO.
What blood type can be found if the mother has type AB blood and the father has type A blood?
If the father is homozygous for the B blood group, giving him the BB blood genotype, and the mother's genotype is AB (the only genotype for the AB blood group), then their offspring could have either the AB or B blood groups. If the father is heterozygous for the B blood group, giving him the BO genotype, then their offspring could have the AB, A, or B blood groups. However, they could not produce an offspring with the O blood group.
