The females will get the disorder or the defective gene if the mother has defective X chromosome or if the father is carrying the same disorder from his father(grandfather). In both the cases the female will be the carrier and have chances to inherit the defect to the offspring. But the female will  not affect as the  male will. As the female has 2 X chromosomes, and hence the dominant X will compensate for the error in recessive X.
