Consider the allelic frequency of the alleles of the bigmouth gene in a population of 10 people. In this population, 2 have the

yan [13]

Answer:

A. q 0.55

Explanation:

Frequency of genotye "BB" $= \frac{2}{10}$ $=0.2$

Frequency of genotye "bb" $= \frac{3}{10}$ $=0.3$

Frequency of genotye "Bb" $= \frac{10-(2+3)}{10}$ $=0.5$

Frequency of bb is represented as " $q^{2}$ " as per Hardy Weinberg's principle.

Thus, frequency q of the recessive allele b is represented by

$q= \sqrt{q^{2} } \\q = \sqrt{0.3} \\q = 0.547\\q=0.55$

Hence, option A is correct.
