Using the Hardy-Weinberg equations, the percentage of carriers of cystic fibrosis is 8.19%.
The Hardy-Weinberg equations describe the relationship between alleles in a population that is fairly constant.
The Hardy-Weinberg equations are given below as;
[tex]p^{2} + 2pq + q^{2} = 1 \\p + q = 1[/tex]
[tex]q^{2} = 0.009\\q = 0.09\\p = 1 - 0.09\\p = 0.91[/tex] Hardy-Weinberg equations
Percentage of carriers = 2pq
Percentage of carriers = 2 * 0.09 * 0.91 * 100 = 8.19%
Therefore, the percentage of carriers of cystic fibrosis is 8.19%.
