Cystic fibrosis is a recessive genetic disease One per 2500

Cystic fibrosis is a recessive genetic disease. One per 2,500 births among Northern Europeans is affected by the disease. If mating is random, then what is the frequency of heterozygotes in the population?

The frequency cannot be calculated because selection violates Hardy-Weinberg assumptions

1/25, or about 4%

1/50, or about 2%

1/2,500, or about 0.04%
