in a population of humans, the frequency of blue eyes is 0.09. if having blue eyes is the recessive phenotype, what is the frequency of the recessive allele?\n0.3\n0.9\n0.18\n0.36
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
