According to the figure, the frequency of affected males is 1 in 5,000 births. Since this is an X-linked recessive disorder, affected females will be much rarer. Therefore, we can assume that the frequency of the disease in the population would be approximately equal to the frequency of affected males.

Calculating 1/5,000 as a percentage gives us 0.02 percent. Therefore, the best estimate for the occurrence of Duchenne muscular dystrophy in all births per year is 0.02 percent or 0.0002. However, among the given answer choices, the closest value is C: 0.015 percent or 0.00015.
