Can two O Negative parents have an A positive child?
No, because to be rh negative, one must have TWO rh negative alleles. The rh factor is recessive. If both parents are rh negative, they must have ONLY rh negative alleles. Therefore they do not have any positive alleles to pass on to their children.
What blood type if both parents are O?
Suffice it to say that A, B and AB are dominant over O, so children will be type O only if they inherit O-type genes from both parents. Children who inherit an A-O combination will be type A, but, remember, they could still pass that O gene off to their children.
Can both parents have O negative blood?
A child with type O blood can have parents with type A, type B, or type O blood, but not type AB. Conversely, if two parents both have type O blood, all their children will have type O blood.
Can I be Rh negative if my parents are not?
Each person has two Rh factors in their genetics, one from each parent. The only way for someone to have a negative blood type is for both parents to have at least one negative factor. For example, if someone’s Rh factors are both positive, it is not possible for his or her child to have a negative blood type.
What are facts about O Negative blood?
O negative blood is a blood group classification. O negative is the rarest of all types and this blood type has no antigens. Antigens include protein, carbohydrates, glycoproteins and glycolipids. This makes it possible for donated O negative blood to be used for transfusion for other blood types,…
Who has O Negative blood?
O negative blood is more common in Caucasians, at 8% of the population. Only 4% of Africans and Hispanics have O negative blood type and only 1% of Asians have O negative. Higher rates of O negative blood type are found in people from Spain, Iceland, New Zealand, and Australia.
What if you have O Negative blood?
If a person with O negative blood can only receive O negative blood. If they are given any other type will cause an immune response in the body. While a person with O negative blood has no A or B antigen in their red blood cells, the plasma still contains A and B antibodies.
Who can O positive blood give to?
Therefore those with an O positive blood type have no AB antigens in the blood, but do have an Rh antigen . This is the most common blood type available, and is commonly sought out for donations. Those with an O blood type can donate blood to those with A, B or O blood types without the worry that their blood will be rejected.
