Answer:

Male or Son

Explanation:

Duchenne muscular dystrophy (DMD) is a disorder caused by RNA mutation. DMD occurs due to an inherent mutation, and it passes through a mother to her offspring. Thus, women are more likely to be carriers of the disease. If a woman has the defective gene and has a son, the son has a 50 percent chance of developing the disease. While a daughter would not develop the disease, she would have a 50 percent chance of being a carrier. Women have two copies of the gene affected by this disease, and men only have one copy of it. If there is an error in this gene, women have a backup copy. Men do not. This form of muscular dystrophy is found in 1 of 3,600 male infants. It generally causes death before the child reaches 25 years of age. As with cystic fibrosis, there is no known cure.
