Answer

Explanation:

Step1: Recall Hardy - Weinberg equation

The frequency of the recessive phenotype ($q^{2}$) is related to the frequency of the recessive allele ($q$) by the equation $q^{2}$ (frequency of homozygous recessive). Given $q^{2}=0.09$.

Step2: Solve for $q$

We take the square - root of $q^{2}$ to find $q$. So, $q = \sqrt{q^{2}}=\sqrt{0.09}$. $q = 0.3$

Answer:

A. 0.3
