None of their children would have the disease, but they would all be carriers. Because the X-linked disease is recessive which mean that it is not the main base so if you use punett squares and would get that all of the genomes are Xx, Xx, Xx, Xx which show you that there is a 0% chance of them two people having a child with that disease but there children could have a child with that disease if they had a mate that had that recessive gene.
