Can a parent with type a positive and a parent with type b positive have a child with o positive blood?

Depending on their genotype this can be possible.
A, B and O refer to the so-called phenotype, which means the actual testable result of genetic information. The genotype on the other hand refers to the actual genetic information of an individual.
There are basically three genes that code the AB0 system, a gene for A, a gene for B and a gene for 0 (actually there are subtypes, but this is not important here).
Everyone has two genes, one on each chromosome of a pair of chromosomes. One gene is inherited form the mother, the other one from the father.
This combination is called genotype. Depending on the combination of genes the four phenotypes are formed. The genotypes are AA and A0 for phenotype A, BB and B0 for phenotype B, AB for phenotype AB and 00 for phenotype 0.
Now to answer the question precisely one would have to know the genotypes of the parents. For example if the parents are genotypes A0 and B0 then the children could have any of the four blood types. The answer would be "yes", as it is possible for the child to to inherit the gene (better a gene) for the positive rhesus factor if both parents have it.
If on the other hand the parents have the genotypes A0/BB, AA/B0 or AA/BB then it is impossible for them to have a child with blood type 0 as no combination would produce the genotype 00 necessary for the phenotype 0.
Conclusion:
It it can be possible. So a child with blood type 0 positive can come from a couple with blood types A positive and B positive. But not all couples with this constellation of blood types will be able to have a child with blood type 0.

Let's assume that the rhesus factor (whether the blood is positive or negative) is automatically positive, because both parents are positive.
Parent 1 could have AO, or AA blood to be type A blood.
Parent 2 could have BO, or BB blood to be type B blood.
If we assume that parent 1 has AO blood and parent 2 has BO blood, then their children have a 25% chance of being O type blood, a 25% chance of being B type blood, a 25% chance of being A type blood and a 25% chance of being AB type blood.

∙ 15y agoNo. Parents of those blood types can only have A or O blood types.

∙ 11y agoyes they can have a child with A pos blood. o group is OO and AB is AB when the two gametes combine they give OA (A positive) and OB( B positive) progeny .

A child is born with type ab blood. which of these statements is true?
A+ Neither parent can have type O blood
Can a person that has o positive blood and a person with a positive blood make a child that has a negative blood?
CAN TWO POSITIVE BLOOD TYPES MAKE a negative blood type
If one parent has blood type O positive and the other has A positive what type will the child have?
Each person has two genes that determine blood type - one you inherit from each parent. There are three versions (know as alleles) of this gene: A, B, and O. Having A and/or B creates antigen molecules on the surface of your blood cells, while having O codes for a protein that is not functional and does not produce surface molecules.Basically A and B are dominant, and O is recessive. So, the possible combinations for a person (showing one from each parent) are:A, A = A blood typeA, O = A blood typeA, B = AB blood typeB, B = B blood typeB, O = O blood typeO, O = O blood type.In your situation, you have one parent whose two genes must be A and B, and the other whose must be O and O (since those are the only combinations leading to AB and O blood types). There are only two possible resulting combinations:A, O = A blood typeB, O = B blood typeSo your child would be A or B blood type.As for positive and negative, it works the same way. The Rh factor (which is what the pos/neg is called) includes one gene from each parent, which positive being dominant over negative. So you're both positive. meaning you could both be +,+ or +,-If one or both of you is +,+ then the child's Rh would have to be positive.If both of you are +,- then there is a 25% chance the child will be negative.Hope this helps!
What does dominant means?
Co-dominance happens when two genotypes are expressed at the same time. For example, one parent can have blood type A and one parent can have blood type B and together produce a child with blood type AB. If two parents have the blood type AB, the child has a chance of being mentally ill.
Can a child with type o blood have parents with ab blood?
"No, if each parent has AB then the child can be A, B or AB but not O." Not exactly. Yes, it IS possible for a child with Blood type O to have a parent with the AB Blood type although it is extremely rare. There are different reasons for this. One is the Bombay blood group. There is also Chimera, or 'vanishing twin'. In certain Asian groups, some of these folks have a rare version of the ABO blood type gene called cis-AB. People with this gene version have an AB blood type but can easily have an O child. I am an O blood type child of an AB blood type parent, although we are not of Asian/European descent. I also have other siblings who are Blood type O so I know it is possible.
Can b positive parent have child with a positive blood?
A B+ parent can have a child with A+ blood. The other parent must be type A or type AB for this to occur.
Can an O positive blood type father parent a B positive blood type child?
no it can not
Can an B positive blood type mother and an B positive blood type father parent an A positive child?
No. The child will be type B or O, it cannot be type A.
Can negative blood type parent and positive blood type parent have an Rh negative blood type child?
yes, absolutely
What type of blood does a child make is one parent blood type is O positive a the other is a positive?
The child could be A+ or O+.
Can a parent with O positive and a parent with O negative have any affect on the child?
If the mother has type negative blood, and the father and child have type positive blood, the mother's blood may begin to attack the child's.
Can an O positive blood type father parent an A positive blood type child?
Yes, if the mother has type A or AB blood.
Can an b positive blood type father and mother parent an o positive blood type child?
yes, blood type is not genetic
What type of blood will a child have if both parents are positive types?
The child will probably be positive, but they can be negative. Each parent has two genes for pos/neg blood type. The parent will have positive blood type if at least one of their genes is positive, but they could both also have negative genes to pass on to the child.
Can an O negative blood type father parent an B positive blood type child?
no
Can both b positive parent have a child with o positive blood type?
yes
Can an B positive blood type mother and a O negative blood type father parent a B positive child?
Yes.
