"X-Linked recessive": This means that the problem causing this disease is carried on the x chromosome. Women have 2 of these, men just one. If a boy has an x chromosome that has this genetic defect, there is no other dna to "cover" this up and that boy will have the disease. Women have 2 copies of dna, and only can be carriers. Mothers can then pass this problem on to their sons, however.
