What blood type would a man have to exonerate him from being the father of Type B child whose mother is Type A?
We are looking for the possible blood types of a "NON"-FATHER.
Parental information:
- Mother type A --can be AA or AO - contributes the A or O gene
- Baby type B --can be BB or BO - has to be BO getting O gene from mom
- Mom type AO + Dad type BB/BO = Baby type AB, BO, OO
- Mom type AO + Dad type AB = Baby type AA, AO, BB, BO
- Mom type AO + Dad type AA/AO = Baby type AA, AO, OO
- Mom type AO + Dad type OO = Baby AA, OO
HOWEVER: There is more to ABO blood typing that just the ABO gene.
There is also an inhibitory gene that will change any genotype into the phenotype O.
Therefore a person with genetically AB blood can be tested as having Type O.
If the father has the inhibitory gene affecting his B or AB type,
then the Type B baby is definitely possible.
What else can I help you with?
If mother is a and father is o what is the child?
If the father is O that means he expresses O because O is recessive and the only way he can be O is to have the OO genotype. The mother may be AO or AA, so the child may be A if the mother is AA, but has a 1/2 chance of being O if the mother is AO. Each parent contributes one allele to the child.
If a mother has O negative blood and her child has A positive blood what type of blood should the father have?
The blood would be A+, the child's is always pretty much what the Father's is.
What blood type a baby will be if father is o and mother is a?
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).
Can a mother with blood group O and gather blood group AB produce O blood group child?
Yes, it is possible for a mother with blood group O and a father with blood group AB to have a child with blood group O. This would occur if the child inherited the O allele from the mother and the O allele from the father.
Can a heterozygous mother with A blood have an O blood child by an AB blood man?
Yes, it is possible for a heterozygous mother with blood type A to have an O blood child when the father has blood type AB. This occurs because the mother provides an O allele and the father provides a recessive O allele, resulting in the child having blood type O.
Probability of son blood group being B if mother is A and father is AB?
25% to be B.
Can a mother with blood type r-a and father with o - positive blood have a chaild with a-a blood type?
He mother and father have nothing to do with the child's blood type
What surprise did Percy's mother have for him when he got home?
She knew about him being a half-blood and about Camp Half-Blood. She told him that his father wanted him to go to a special camp. Also, Percy's mother tells him that his father fid not know him as a baby.
Could a father with a blood group ab have a child that is O blood group?
Absolutely. A child will either have its mother's blood type or its father's blood type. If the mother's blood type is NOT O, then someone else is the father.
If mother is a and father is o what is the child?
If the father is O that means he expresses O because O is recessive and the only way he can be O is to have the OO genotype. The mother may be AO or AA, so the child may be A if the mother is AA, but has a 1/2 chance of being O if the mother is AO. Each parent contributes one allele to the child.
Can a baby be born with blood type o if the father is blood type o and the mother blood type a?
Yes. The father's blood type must be oo. The mother's blood type could either be Ao or AA (both of these are blood type A). If the mothers blood type is Ao, she could give the o gene to the baby, resulting in the baby being type oo (or type o). (In order to have blood type o, you must have an o from your mother and an o from your father.)
If the father's blood type is A positive and the mother's blood type is O positive can the child's blood type be O negative?
No, because a baby gets their blood from their father, not their mother.
What blood type will the baby have with a mother with type a blood and father with type ab blood?
Possible blood types of the child with a mother who has A blood type and a father who has AB blood type are A, B, and AB. :)
Can a father with A-negative blood have a child with A-positive blood?
Yes, a father with A negative blood can have a child with A positive blood. If he does, the mother must have a positive Rh factor, and the mother's blood type may be any of the possibilities.
Can a mother of o blood group have a healthy child with a father o?
can a mother of o blood group have a healthy child with a father type o
Can a mother with B positive blood and father with O positive blood have a baby with B positive blood?
Yes, a mother with negative and a father with O positive can have a baby with B positive. If they do, the mother must have blood type B or AB.
If mother and father is A blood group can child be B positive?
If the mother is A, and the father is A, then the child will only have A antigens and will thus be blood type A. If father or mother are AB, then the child can end up with AB, A, or B blood type. http://en.wikipedia.org/wiki/Blood_type
