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?

The possible blood types for their children are A positive or O positive. The child inherits one blood type allele from each parent, so they can receive either the A allele from the A positive parent or the O allele from the O positive parent.


Can parents who are B negative and O positive have a AB positive child?

No, it is not possible for parents with blood types B negative and O positive to have a child with AB positive blood type. The AB blood type requires an A allele from one parent and a B allele from the other, which is not possible in this case.


Can a positive and o negative be full siblings?

Yes - but both of the parents would have needed at least one O allele and one Rh negative allele. If either parent was homozygous AA or OO (or homozygous Rh positive), then this would not be possible.


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.


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 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 parents who are B negative and O positive have a AB positive child?

No, it is not possible for parents with blood types B negative and O positive to have a child with AB positive blood type. The AB blood type requires an A allele from one parent and a B allele from the other, which is not possible in this case.


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 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.


Can a person that has o positive blood and a person with a positive blood make a child that has a negative blood?

Yes, it is possible for a child to have a negative blood type if both parents are carriers of the Rh negative gene, even if one parent is O positive and the other is A positive. Blood type inheritance is determined by a combination of both parents' blood types and Rh factors.


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 a positive and o negative be full siblings?
