The frequency of cystic fibrosis, a recessive genetic disease, is one per 2,500 births among Northern Europeans. Assuming random mating, what is the frequency of carriers?
Added by Ignacio B.
Step 1
Cystic fibrosis is a recessive genetic disorder, which means that an individual must inherit two copies of the mutated gene (one from each parent) to manifest the disease. If an individual inherits only one copy of the mutated gene, they are a carrier but do not Show more…

In Northern European populations, the incidence of cystic fibrosis is about 1/2500 or 0.0004. What is the frequency of carriers (heterozygous individuals that have a disease-associated allele, but don’t have the disease) in the population?

Cystic fibrosis is an autosomal recessive disorder. If a person is homozygous for the recessive allele, he/she exhibits cystic fibrosis. In the United States, approximately 1 in 2500 children are born with the disease. Assuming Hardy-Weinberg equilibrium, what proportion of Americans are carriers for cystic fibrosis?

Cystic fibrosis is an autosomal recessive disorder (i.e., if a person is homozygous for the recessive allele, he/she exhibits cystic fibrosis). In the United States, approximately 1/2500 children are born with the disease. Assuming HWE, what proportion of Americans are carriers for cystic fibrosis?
