How does a child get B negative blood?
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.
Can I be O positive if my parents are A and B?
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 a child have a different blood type than both parents?
Yes, a child is able to have a different blood type than both parents. Which parent decides the blood type of the child? The child’s blood type is decided by both parents’ blood type. Parents all pass along one of their 2 alleles to make up their child’s blood type.

Can 2 O positive parents have an A positive child?
Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations. How does this happen?
Can blood type A and B make O?
Can an AB father and an A mother have an O baby? Yes they can. An AB parent can indeed sometimes have an O child. But it is by no means common.
CAN A and B have a baby?
Yes they can. An AB parent can indeed sometimes have an O child. But it is by no means common. In fact it would be fair to say that it is exceedingly rare.
Is it possible for parents with type A and or Type B blood to have a child with type O blood?
Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there’s 1 in 4 or 25% chance for a child to have OO, or blood type O. How did I get a 1 in 4 chance?
How rare is Rh negative B negative?
How rare is B negative blood? B negative blood is one of the rarest blood types as just 2% of our blood donors have it. In comparison, 36% of donors have O positive blood which is the most common type.
Is B positive blood rare?
How rare is B positive blood? This means only 8% of donors have B positive blood. In total, 10% of people belong to blood group B, making it one of the least common blood groups.
What does B negative blood mean?
An individual with a B negative blood type has antigen B but with no Rh antigen on the blood. Having the presence of B antigen and the absence of Rh antigen, B negative blood type can only receive B- and O-. A transfusion with the usage of any other blood type can initiate an immune response.
