In brief: Depends

He can only pass the fragile x to a daughter, 100% of which would be carriers and might have minor learning problems.
They could then pass the fragile x to their male offspring. If the baby is male he would be unaffected since they got the Y from dad.

In brief: Fragile X Sundrome

The genetics of fragile x syndrome are little complicated.
It x linked dominant condition with variable expression.It does not followusual pattern for xlinked condition it depends whether the father is a carrier or he has full mutation.He may pass the carrier gene to the daughters and they will be normal but carrier of the gene.The males can not pass the full syndrome.
