What blood type would a baby have if both parents have blood type O positive?

The gene for blood type O is recessive. The mother can only have the phenotype O if she has the genotype OO.
The gene for blood type B is dominant, the father has the phenotype B, but can have the genotype BB or BO.
If the father is genotype BB, the child will be B + O = BO genotype; hence B phenotype.
If the father is genotype BO, the child can be B + O = BO genotype; hence B phenotype (50% chance). Or O + O = OO genotype (O phenotype, 50% chance).
* Phenotype = displayed trait that can be found with a simple blood test.
* Genotype = genetic make up (one part from each parent), this requires a DNA test to be confirmed; however, it can sometimes be deduced by logic.

What blood type do the parents have to be to make an A positive baby?
One of the parents must be A or AB, and one must be positive.
What are parents blood group with their first baby is of blood group o negative?
a positive
Can Two o positive parents have a ab positive baby?
No they cannot. If a parent is O, that means that their blood is IOIO, a child from this pairing would have inherited both O's from the parents.
If a mother has a positive blood and father has o positive blood can the baby have ab negative blood?
it it possible if someone from either parents' family has had it or haves it because of genes
Can an AB positive blood type and a o positive blood type a produce an o positive child?
No, because the domonite blood type would be AB positive. So you would most likely get a baby that is AB positive.
Can two parents with o positive blood have a baby with b positive blood?
Another has said: no chance. One of the parents must be b positive.
Can a baby be born with positive blood if both parents have negative blood?
No, it is not possible.
Can two parents with AB positive blood harm the baby?
No, it will not.
What blood type do the parents have to be to make an A positive baby?
One of the parents must be A or AB, and one must be positive.
If two parents have A positive blood can the baby have O positive?
yes it is possible, blood groups do not work that way.
Can two parents with O positive blood have a a positive baby?
No, this can't happen, if two parents are O blood type, all kinds will be O.
Can parents with AB positive and A negative blood have a baby with 0 negative blood?
Yes
What are parents blood group with their first baby is of blood group o negative?
a positive
When Parents with b positive and o positive blood have baby with o negative blood group?
I'll wait for you to ask the question. Positive parents can have a negative baby as positive is dominant so they may both have one positive and one negative gene and the baby gets the two negative genes.
Can Two o positive parents have a ab positive baby?
No they cannot. If a parent is O, that means that their blood is IOIO, a child from this pairing would have inherited both O's from the parents.
If both parents have a blood type of O positive will the baby have the same blood type?
The baby can have either O- or O+ blood type.
If one parent has A positive blood and the other had A positive blood what type will the baby have?
The blood type would be A positive.
