Unformatted text preview: both sides!).] Some applications The Hardy Weinberg equilibrium can be used to estimate genotype and gene frequencies from limited data. • For example, for a recessive condition: if the frequency of affected people is f then the gene frequency q = f ½ and the frequency of carriers will be 2pq (and because p is close to 1 this will be more or less 2q). For cystic fibrosis, the frequency of affected children is about 1 in 2000, therefore q = [1/2000] ½ = 0.0223, therefore the frequency of carriers is approximately 2q = 0.0446 or one in 22....
