Since blood type A and B are codominant, it means that the people who have blood type AB only have genes of A and B. They do not have the gene for blood type O.

![\left[\begin{array}{ccc} &A&B\\A&aa&ab\\B&ab&bb\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%20%20%26A%26B%5C%5CA%26aa%26ab%5C%5CB%26ab%26bb%5Cend%7Barray%7D%5Cright%5D%20)
From this, we can see that the only possible blood types their child could have are A, B, or AB. So, O is not possible.
