    remember, females have two X chromosomes....the X without the faulty gene, over rides the one that does...that makes it recessive....dominant is when the faulty gene overrides the non faulty.....

    Here is an advanced genetics wizard that will calculate the genetic makeup of offspring. Offers no educational explanation, but is interesting to use:
