Question

The Hardy-Weinberg principle is written as an equation: p2 + pq2 + q2 = 1. What does the q represent?

Answer 1

Answer:

The correct answer option is: frequency of the recessive allele.

Explanation:

When there are no mutations, no selective forces, no gene flow, no non-random mating and large population size, the population is said to be in Hardy- Weinberg equilibrium.

When Hardy-Weinberg equilibrium is met, it is written in the form of an equation which is as follows:

$p^2+2pq+q^2=1$

where $p^2$ represents the frequency of the homozygous dominant allele, $2pq$ is the frequency of the heterozygous  allele while q or$q^2$ represents the frequency of the homozygous recessive allele.
