What blood types are possible from an B positive and A positive parent?

It depends what the second gene for each parent is. Bx+ and Ax+ is the information given.
The x could be B for Bx and A for Ax. The x could also be O for both. So AA and BB or AO and BO.
In all cases the cross between AA and BB would produce AB.
For the cross between AO and BO, the result would be AB, BO, AO, and OO in a 1:1:1:1 ratio.
If the cross is AA and BO, the result would be AB and AO in a 1:1 ratio.
If the cross is BB and AO the result would be AB and BO in a 1:1 ratio.
In all cases the Rh factor would be +

If one parent is A positive and the other is O positive what possible blood types?
AO positive is the only possible blood type.
Can a person having her father's blood group o positive and her mother's blood group ab positive have her blood group also ab positive?
Yes it is possible. One of the parents would have to be Type A (AO) and one parent would have to be Type B (BO). Also one parent would have to be positive and one would have to be negative (referring to Rh). It doesn't matter which parent is which and it also doesn't matter if it is A+ and B- or A- and B+. Either of these two situation could produce all four different blood types.
What are the possible blood types of a father if the offspring is A positive and the mother is O positive?
The first parent would be heterozygous for type A. The second parent would have to be heterozygous for type A, heterozygous for type B, or blood type O. The positive or negative is unable to be determined because positive is dominant so the first parent is positive then the baby will be positive with out a doubt so there is no way to find out the second parent's positive or negative.
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! :)
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.
If one parent is A positive and the other is O positive what possible blood types?
AO positive is the only possible blood type.
Can parents with B positive and O negative have an A positive child?
No. The parent's possible blood types are BO and OO. If the child is AO something is incorrect. Neither parent has an A to pass along.
Can parents with A positive and B positive have a O negative child?
No. The parent's possible blood types are BO and OO. If the child is AO something is incorrect. Neither parent has an A to pass along.
Can parents with A positive and B positive have a child with B negative?
No. The parent's possible blood types are BO and OO. If the child is AO something is incorrect. Neither parent has an A to pass along.
Can a parent with ab- blood and a parent with o- blood make a baby with a plus blood?
No, in this scenario the possible blood types for the children are A- and B-. Positive refers to the presence of Rh factor in the blood. The Rh factor has to come from somewhere.
Can a ab and o positive have a baby o positive?
No, Neither parent in this situation carries the B gene. The only possible blood types for offspring would be either A or O.
What are blood types that are possible to have?
The blood types are A, B, AB and O. Rh positive or negative are also blood types possible. What blood type we will have is inherited from our parents.
Can parents with b positive and o positive blood have a child with b type blood?
Yes. parent with B and a parent with O blood traits can have the following blood types in their children : B, O, BO
What are the possible blood types for a child with a mother who is O positive and a father who is B positive?
B positive
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 blood types can be formed by crossing A genes with B genes?
If the parent's blood type is A and B, respectively, the possible blood type of their child are A, AB, B and O.
Can a person having her father's blood group o positive and her mother's blood group ab positive have her blood group also ab positive?
Yes it is possible. One of the parents would have to be Type A (AO) and one parent would have to be Type B (BO). Also one parent would have to be positive and one would have to be negative (referring to Rh). It doesn't matter which parent is which and it also doesn't matter if it is A+ and B- or A- and B+. Either of these two situation could produce all four different blood types.
