What blood types would your parents have to be to have a child with A positive blood type?

Discounting rare but possible mutations the following holds true. Parents blood groups A and A, A and B, A and O, B and B, B and O, O and O can produce type O blood in their children. The rhesus factor (Rhesus positive/rhesus negative) depends on the rhesus pairing in the parents as follows: Father rhesus positive, mother rhesus positive or rhesus negative = rhesus positive or rhesus negative Father rhesus negative, mother rhesus positive = rhesus positive or rhesus negative Father rhesus negative, mother rhesus negative = rhesus negative Example: A rhesus positive father and rhesus positive mother of blood type A and O respectively could produce an O positive child, as could a rhesus positive father and rhesus negative mother both of blood group O.

Whoooo... I think thats all the possible combinations. A couple with any of the above blood types could have an A+ child.
NOTE: The H antigen is often called the O antigen by lay-people

Can parents with blood group o positive and a positive have child with a positive blood group?
yes, for the blood types there are 2 genes that decide ABO/+- the ABO is based on a gene with 3 genotypes, which are i, IA and IB if a person has ii, they have O blood, if they have iIA or IAIA they have A blood, if they have iIB or IBIB they have B blood and if they have IAIB they have AB blood positibe/negative is the rhesusfactor, it actually works with 3 genes(C, D, and E), but anything other than cde/cde will give rhesus-positive blood, so a parent with ii-cde/cde will have O-negative, and iIA/CDe/CDe will give A-positive, the only 2 blood-types the children can have with this set of parents are A-positive and O-positive
Can someone with B negative blood type have a child with someone with b posititve blood type?
Absolutely - all blood types can have children together. The only problem relating to these blood types for pregnancy would be if the mother is negative and her first child was positive. Then there may be a problem if her second child is also positive.
If both parents are A positive can a child be B positive or negative?
Maybe. A child will have either the mother's blood type or the father's blood type. If the father is B+ and the mother is A- then it is possible that the children have the same father. So it all depends on both parent's blood type.Source: I am a 2nd year nursing student, and we had a long discussion about this subject last semester.
Is it possible to have a child with o negative blood and mother o positive then father belongs to which blood group?
Both the O and Rh negative types are recessive to the other blood types and the Rh positive trait. Both parents can be any blood type except AB and produce a child with type O blood, and can both be Rh positive and produce a child with Rh negative blood type. Since recessive traits can be carried through multiple generations without ever manifesting as the phenotype, parentage can't be ruled out when recessive traits finally manifest under the right circumstances.
How can two parents with blood types A and O have two children with blood types A and O?
The definition of heterozygous A means the parent has an A gene and an "i" or basically an "O" gene. The heterozygous B parent has a B gene and an "i". So the genotypes are Ai and Bi. If you set up a Punnet square, the four possible gene selections are AB, Ai, Bi, or ii. If the child has "ii" then it is said the child has O blood. The AB child has AB blood, the Ai child has A blood, and the Bi child has B blood. (Remember this scenario does not take into account the negative and positive part of blood types. Such as O- and O+ both have O blood but one is O negative and the second is O positive. Your question didn't ask this but I have seen many "trick" questions in biology classes where the negative and positive blood types are part of the answer.) Hope this helps! :)
Can parents who have B negative and O positive blood types have a child with O positive blood?
No, they will have a O negative child.
Can parents both blood type A positive have a child A positive blood type?
In that given scenario, the possible blood types of the child are: A-, A+, O+ and O-.So Yes, it is possible to have a child with A positive with 25%.
What would your parents blood types have to be to have a child with b positive?

If both parents have 0 positive blood types could child have type A?
No.
Can a child have o positive blood if the parents blood types are b positive and o positive?
Yes, in that "O" is the result of the dominant gene.
Can two parents with O positive blood have a A positive child?
No, it is impossible to get an A-type from two O-types.
Can parents both blood type O have a child with B positive blood type?
It must have one of the true parents blood types.
How can a child's blood type be b positive if mom is b positive and dad is a positive?
You could have several children with different blood types. you get your blood type from either parents or even grand parents.
Can parents who have B negative and O positive blood types have a child with B positive blood?
Yes. They can have B+, B-, O+, and O-.
Can two O positive blood types have a child with A negative blood?
Yes. The geneotype for both parents must be AO+- for the child to be OO--
If both parents are blood type A positive and B positive will the child have any problem?
It is always possible, but normally not (as was the case with myself). The Child Can have A, B, or AB blood types.
Can a child have a negative blood types if the parents are both a positive?
Yes! Parents have two genes for pos/neg blood type, and only one of them needs to be positive for the parent to have positive blood type. Most positive-blooded people have one positive gene and one negative gene. If both positive parents pass on their negative gene, they can have a child with a negative blood type.
