Is it rare for an A positive parent and an O positive parent to have an A negative child?
It's rare, but can easily be explained by genetics.
The A positive parent could be AA or AO for blood group, and the O positive parent would have to be OO for blood group. Both parents would have to be heterozygous for rh factor, Rh+ Rh- . So the A negative child would have to have inherited an A and O allele from the parents, and an Rh- allele from both parents. This gives the phenotype of A negative.
What else can I help you with?
Can an A negative parent and a A positive parent have a child who is AB negative blood type?
it can be rare only
Can o plus an o negative have a child with type a blood?
No, if both parents are type O, the child must be type O. However, since one parent is positive and the other is negative, the child could be either positive or negative.
Can a positive and o positive have a negative child?
yes, but rare.
Can o positive and o negative can have a positive child?
yes, but rare.
What type of blood do I have if my parents are A negative and B positive?
If your parents are A negative and B positive, you could have blood type A or B, as you inherit one blood type allele from each parent. The Rh factor (positive or negative) would depend on whether you inherit the Rh allele from your B positive parent.
Problems in child delivery when father is o negative?
Blood type and Rh factor do not affect the health of a child except in rare conditions, usually due to incompatibility with the mother and child when the father and are positive but the mother is negative.
If one parent has o neg and one o pos can you have a B neg?
An O mother and an O father will always have an O child. They cannot have A, B or AB. As far as the Rh factor the baby can be positive or negative. There are rare instances when this will not be accurate. In the case of a mutation, the blood typing may not hold true in the question of parentage. Ask before you act! A DNA test will give a final definitive answer.
Is ab blood type a positive?
yes there is but it is rare
Is it possible for two A-positive parents to have an O-negative child?
Yes, it is quite possible. It does require both parents to have AO(+-) genotypes, which is somewhat rare, however.
Can 2 parents with A positive blood have a child with A negative blood?
No. A child of A and O parents would have A or O. For the child to be AB the parents would have to be A and B Or at least one would have to be AB. The O parent cannot be the parent - you might want to follow up with your doctor for further testing.
Is it rare for 3 of 5 kids to have o positive blood type and other 2 kids have a positive blood type with same parents?
No, it is not rare for 3 out of 5 kids to have O positive blood type while the other 2 have A positive blood type. Each parent passes on one blood type allele to their child, so it is possible for variations in blood type within siblings to occur based on the combination of alleles each child inherits.
My blood group is o positive kel negative is this rare?
Having O positive blood with an Rh(Kell) negative blood type is relatively rare. The O positive blood type is the most common blood type, but the combination of O positive with Kell negative is less common. It is important to discuss any concerns with your healthcare provider regarding blood compatibility for any future medical needs.
