The parents could be a dominant A with an o and a dominant B with an o. The A and B are dominant, and the o's are recessive. The children can get 2 o's, one from each parent and they would then have o blood type.

Yes.

The different blood types are A, B, AB, and O. But, both A and B have two variations. A can be either AA or AO, while B can be either BB or BO. AB can only be AB and O can only be OO. So, if the B parent has BO blood and the A parent has AO blood, each can give an O, resulting in OO blood, which would be blood type O.

Here is a chart of the possible results if the parents are AO and BO:

......B O

A AB AO

O BO OO

So, these parents can produce children with all four blood types: AB, A, B, and O.

And, since one parent is Rh-negative and one is Rh-positive, the children could be either negative or positive.

Yes. Rh factor is a phenotype similar to the blood type. Positive is dominant and so the possible genotypes are ++ or +-, whereas for negative it can only be --. If the parents are both +- they can produce ++, +-, or --. There is a 25% chance that these parents would have an O- child. Of course if one of the parents is ++ while the other is +- they can only produce ++ or +-, making the children O+. Finally, if both of the parents are ++ then they can only produce ++, making O+.

--

The above answer is a very confusing way of simply saying "A parent with O+ and a parent with O- have a chance of having a child with one or the other."

But when you ask whether combining O+ and O- can create either a + or -, the answer is no. Blood is not math. Either the inherited Rh antigen is present or it isn't. If it is, you get +, if it isn't, you get -. It's that simple.

Yes. O blood is a recessive gene. If someone has type A blood it means their genes are either AA or AO and if they are type B it means they either have BB or BO genes. If a person with type A blood is has AO and a person with type B blood has BO, they could have a baby with OO genes giving the baby type O blood.

No, only O blood can receive O type blood. O type is the universal donor as all blood types can receive type O blood. Positive blood types can receive both positive and negative blood but negatives can only receive negative. AB positive is the universal recipient as they can receive all blood types. A can only receive A and B can only receive B.

A person with O- blood can only receive O- blood - O is the universal donor, not the universal receiver.

Is there a posibility to have a child that is blood type -A A couple who are blood type B and blood type O?

No. It is not possible for a child to have A if the parents are O blood type. If both parents have type O blood, then their children will also have type O blood. However, two parents with type A or type B blood (both the same or one of each) can sometimes have a child with type O blood. That is because the gene for type O blood is recessive. But they must carry the O type. However, two parents with type AB blood can have a child with type A, type B, or type AB blood, but cannot have a child with type O blood.


If you have o negative blood do your parents have o blood too?

They could, but they don't need to. Both of your parents must have at least one O allele, meaning neither can have type AB blood. They must be either BO, AO or OO to produce a child with type O blood.


Can 2 type o blood types have a blood type a child?

Parents of blood type O can only have children with blood type O. Because type O is recessive, you know that the parents are homozygous O.


What blood types can O negative donate to?

ABO stands for 4 most common blood antigens called A, B, AB and O. The person with Type A has antigen A, type B has antigen B and type AB has both A and B antigens. Type O has no A or B antigen. Antibodies against these two antigens are found thus type A has anti B, type B has anti A, type O has anti A & anti B. Type AB has no antibodies. They can receive blood from any type. Rh neg can go to Rh +/- Rh pos can only go to Rh+ Type O neg blood is called the universal donor can be given to A, B, AB, O with Rh+ or Rh- Type O pos blood can only go to O, A, B & AB pos Type O blood can receive donation only from type O. The 'universal donor' applies only to packed RBC's and not to whole blood products due to the anti bodies A and B found in serum. Type A, B, or AB given type O whole blood would produce a hemolytic transfusion reaction due to the antibodies found in the serum. Type A blood can receive blood from donors of type A and type O blood. Type B blood can receive blood from donors of type B and type O blood. Type AB blood can receive blood from donors of type A, type B, type AB, or type O blood.


Can man with blood type ab and a woman with a blood type o produce with a blood type o?

No. A and B are dominant and O is recessive. Here are possibilities that can occur: AB and BO --------------- A B B AB BB O AO BO AB and BB --------------- A B B AB BB B AB BB

What is the only genotype that will produce O type of blood?

The gentotype is ii that will produce blood type O. The allele i is recessive, so both parents must have at least one i allele, and the child must be ii (double recessive) to be blood type O. The parents' blood types do not have to be type O- the genotypes Ai (blood type A, as A is dominant), and Bi (blood type B) can produce blood type O offspring, as long as the child inherits the i allele.

Yes, an individual with blood type B can produce an offspring with blood type A. The explanation for this is that a mother with the blood type A can have a child with a father who has a blood type of A or AB and produce a child with type A blood.
