Is it imposible for the X chromosone of a son to have come from the father?

Explanation:

If a male who has an X-linked condition has a son, his son will never inherit the changed gene on the X chromosome. This is because men always pass on their Y chromosome to their sons (if they passed on their X chromosome they would have a daughter).
