Can two O+ parents have an A- baby?

Question

Can two O+ parents have an A- baby?

Answer 1

No.

One parent would have to be an A and the chances of the baby having either O or A blood group would be 50-50 if one parent had O and the other had A.

Two parents with O blood could not have a baby with any other blood group.

Answer 2

Yes, but it is extremely rare: http://en.allexperts.com/q/Genetics-1795...

Answer 3

No the baby has to be either its mother or its fathers blood type. So one of the A- baby's parents would have to be A-.

Answer 4

Nope.  O+ means that neither parent has an A or B antigen, so any baby would also be O.
