How common is blood group B Rh D Negative?
i think that 15% of people in the whole world have this blood group
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.
Can parents with O positive and B positive blood give birth with A negative blood?
Actually it could happen if one of the parents was a chimera but the chances of that being the casewould be rare.
Can you have O Negative blood if your mother has O Positive and your dad has A Positive?
Yes, if the father's genotype is AO, and both of them have +- genotype. However, this would be very rare.
What blood types would your parents have to be to have a child with A positive blood type?
Discounting rare but possible mutations the following holds true. Parents blood groups A and A, A and B, A and O, B and B, B and O, O and O can produce type O blood in their children. The rhesus factor (Rhesus positive/rhesus negative) depends on the rhesus pairing in the parents as follows: Father rhesus positive, mother rhesus positive or rhesus negative = rhesus positive or rhesus negative Father rhesus negative, mother rhesus positive = rhesus positive or rhesus negative Father rhesus negative, mother rhesus negative = rhesus negative Example: A rhesus positive father and rhesus positive mother of blood type A and O respectively could produce an O positive child, as could a rhesus positive father and rhesus negative mother both of blood group O.

Is AB positive a rare blood group?
Yes, less than 3% of the population. AB negative is rarer still.
Is ab blood type a positive?
yes there is but it is rare
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 blood is rare?
Having a rare blood group (such as AB negative) would make someone a rare blood donor.
Can an A negative parent and a A positive parent have a child who is AB negative blood type?
it can be rare only
What is the rarest blood type among humans?
AB Negative is the most rare of the 8 blood types. The full list of types is A, B, Ab,and O. Within that group there are both positive and negative groupings.
How common is blood group B Rh D Negative?
i think that 15% of people in the whole world have this blood group
What are rare blood types?
Rare blood types are O negative and AB negative. B negative and AB positive are also fairly rare blood types. O negative is known as the universal donor blood type because it is compatible with any other blood type.
Why is Rh negative blood so rare in the human population?
Rh negative blood is rare in the human population because it is a genetic trait that is not as common as Rh positive blood. The Rh factor is inherited from our parents, and the gene for Rh negative blood is less prevalent in the general population. This makes Rh negative blood less common compared to Rh positive blood.
Is 'a' negative a rare blood group?
O neg is the second rarest blood group (AB neg is the rarest). It is more valuable than rare, as it is a universal donor.
Why is o negative blood group rare?
O negative blood group is rare because it lacks the A, B, and Rh antigens present in most other blood types. Only 7% of the population has O negative blood, making it less common and in high demand for blood transfusions since it can be safely transfused to individuals with any blood type.
Is a positive blood rare?
No, positive blood types are actually quite common. The most common blood type in the world is O positive.
