Yes. Blood types are only partially dependant on the parents blood type. The parents geneology is more important and only one parent with the recessive negative rh gene can pass it to a child. as for the type (A, B, AB, O) that again is dependant on the genetics of both parents. It is easily possible. If you are in doubt get a DNA test done. There are many hospitals and clinics who will for this for an affordable, if not free, price.

For instance look at this cross:
· Type AB - made up of one A gene and one B gene
· Type O - made up of two OO genes
· Mom AB + Dad OO = Baby type AO or BO
The children of this AB X OO mating will have neither blood type of the parent.
Instead, they have a combination of the parental genes.
There are other crosses that will give one sibling A and the other B. The parents, in combination, must contribute the A or B genes.
