10. Write the 2 Hardy-Weinberg equations. Use the equation to calculate the percentage of carriers of cystic fibrosis (a recessi
Firlakuza [10]

Using the Hardy-Weinberg equations, the percentage of carriers of cystic fibrosis is 8.19%.

<h3>What are the Hardy-Weinberg equations?</h3>

The Hardy-Weinberg equations describe the relationship between alleles in a population that is fairly constant.

The Hardy-Weinberg equations are given below as;

p^{2} + 2pq + q^{2} = 1 \\p + q = 1

q^{2} = 0.009\\q = 0.09\\p = 1 - 0.09\\p = 0.91 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%.
