According to a recent study, 1 out of 50,000 people will be diagnosed with
cystic fibrosis. Cystic fibrosis can be caused by a mutant form of the CFTR gene
(dominant gene symbol is F and mutant is f).
A. Using the rate of incidence above, what is the frequency of carriers of the
cystic fibrosis allele for CFTR in the US? (3 pts)
B. In a clinical study, 400 people from the population mentioned in (A.) were
genotyped for BRCA1 Listed below are the results. Are these results in Hardy-
Weinberg equilibrium? Use Chi Square to show whether or not they are. (3 pts)
