What would your parents blood types have to be to have a child with O positive blood type?
At least one parent would have to have an RH Positive blood type. Beyond that you can not tell. Because the O trait is a recessive trait, either parent could have A or B or O blood, since, for example, a parent with A blood could have one A gene and one O gene that together would express the A trait. That parent's child could inherit either the A gene or the O gene. The other parent could have B based upon one B gene and one O gene that together would express the B trait. That other parent's child could inherit either the B gene or the O gene. Only if the child of both parents inherited an O gene from each parent, would the child have O blood.
As to the RH factor, it is a dominant trait, so that if the child has the trait expressed, it would have to have been in one of the two parents.
Hope this helps.
What else can I help you with?
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%.
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 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.
