Can an O positive parent have an A negative child?

Yes this is definitely possible. In this case, the most likely explanation is that dad is a carrier for being Rh- and mom is a carrier for blood type O. What happened was that dad and mom each passed both an O and an Rh negative to the baby. The end result is an O negative child.

Can an O blood type mother have an AB child?

child cannot be explained in terms of the usual inheritance pat- terns. 3 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. Typically, an O mother would produce either an A, B, or an O infant.
