If a mother has Type A blood and her son has Type B blood what blood types could the father have?

You cannot say for certain. Without knowing the exact genetical make-up (genotype) of both parents, the child could belong to any blood group (type): A, B, AB, or O.
If the mother has blood group B, her genotype must be either IBIB or IBi. The father must, similarly, be IAIA or IAi. The child could therefore have any of the following genotypes:
IAIB (type AB)
IAi (type A)
IBi (type B)
ii (type O)
We cannot calculate probabilities without knowing parents' genotypes

∙ 14y agoIt all boils down to the specific alleles each parent possesses and which ones actually pass on to the child. A few generalizations can be made, however, that can narrow down the possibilities of the child's blood type.
- If the father's ABO alleles are BB as opposed to BO, or the mother's are AA as opposed to AO, then the child cannot be type O, as this requires both parents to pass on an O allele. If neither parent has an O allele, then the child will be type AB.
- If either parent's Rh alleles are ++ (as opposed to +-), then the child will be Rh+, as an Rh- requires both parents to pass on an Rh- allele.

∙ 14y agoThe baby can be type A, B, or AB. It takes 2 genes to express the blood type. The mother could be BB or BO. If the father's A combines with the mother's O then the baby will be AO which is expressed as A. It may be possible to figure out if the mother is BB or BO by learning the blood types of her parents.

∙ 10y agoWe are looking for the possible blood types of the FATHER.
Parental information:
- Mother type A -- can be AA or AO - contributes A or O gene
- Baby type B --can be BB or BO - mother will contribute the O gene
- Mom is AO + Dad is BB/BO = baby BO, AB
- Mom is AO + Dad is AB = baby BO, AO, AA, AB

∙ 13y agoIf the mother is homozygous for B (BB), the child can be either AB or B.
If the mother is heterozygous for B (iB), the child can be either AB, B, or A.

If both your mother and father have negative blood types does that mean you will too?
no but there is a average chance you will :)
Can a heterozygous mother with A blood have an O blood child by an AB blood man?
no. The possible blood types of an offspring are A, B, and AB. in order to have a recesive gene have a possibility of appeaing in the child oth the mother and father must carry the gene.
What are the possible blood types the baby could have if the mother is type O-positive and the father has the rh-negative blood type?
The rh factor is different from blood type. If the mother is RH positive and the father is RH negative, the baby can be either RH positive or RH negative. That is RH factor. It is different from blood type. If the mother is blood type O, and the father is blood type O, the baby will be type O. However the father can be type A, B, or AB. In that case, the baby may be one of those.
If a mother with blood type A and father with blood type A is there a chance there child's blood type is AB?
100%, but just the fact that your blood type is A, doesn't mean that your genes are AA. If your genes are AO, you would still be type A, because the O gene only expresses itself if both genes are O. So unless you are certain that your blood types are AA and BB, the children could have other types. For example, parents with AO and BO genes could produce children with A, B, AB, or O blood types.
What are blood types of offspring if mother is O plus and father is O?
The blood type for both parents must be OO since the O blood type is recessive. That means the child will definitely be O. The mother, since she has an Rh factor of + must be either ++ or +-. The father must be --. So, if the mother is ++, then the child will be O+. If the mother is +-, then there is a 50% chance that the child is O- and a 50% chance that they will be O+.
What blood types could children have from a mother and A- father?
the only way to tell your blood type is to have a test
What is the role of blood typing in paternity testing?
To determine whether or not the alleged father could be the true father, the blood types of the child, mother, and alleged father are compared.
If your father has type A blood can you have type O blood?
Yes, that is entirely possible. Your father could be AA or AO, meaning your possible blood types (depending on your mother's) are: A, B, AB, and O.
What are the blood types for a father with type A blood and a mother with type B blood?
A or B or ab blood
Can father blood type a and mother blood ab have blood b baby?
what is coyote blood types
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. :)
A- father and a O- mother gives what blood types?
AO which is the same as A
Can two baby's from same father with a and mother has o have two children with different types of blood one has a the other o?
it could be.
Is it possible to have a child with blood type AB when the mother having blood type O and the father having blood type A?
If the mother has O type blood and the father has A then the child could not have AB blood type. The possible blood types for these two people children would be type A and O. Lookup a Blood Type Calculator on the net and type in the different blood types and see the results.
If the mother have O and if the baby has B what is the father?
If we are talking about blood types, the father can be B or AB.
Bothe the mother and father have blood type O What are the possible blood types of the offspring?
O
Should a child with A positive be same as the mother?
Blood types are received from the mother and father, so the child can be the same type as the mother if the father's type allows it.
