Q. Can an O positive have an AB child?
An AB and O couple producing an AB child cannot be explained in terms of the usual inheritance patterns. One would not expect the cord blood result to be AB when the mother is type O, however, in very rare instances, such as the cis-AB blood type, it is possible.
Q. Can a child have a different blood type than both parents?
While a child could have the same blood type as one of his/her parents, it doesn’t always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B. These two types are definitely different than parents’ blood types!
Q. Can two O-positive parents have AB 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?
Q. Can two a positives make an O-positive?
Yes, it is possible for parents to have type A blood and their child to have type O blood. The positive and negative of the blood is called the rH factor and is separate from the type of blood. Type O is a recessive blood type. Each person has two genes for a trait, one from the mother and one from the father.
Q. What if Mother is positive and father is negative?
When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.
Q. Is AB positive a rare blood type?
How rare is AB positive blood? Just 2% of donors have AB positive blood making it one of the rarest blood types in the country.
