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:
[tex]p^2+2pq+q^2=1[/tex]
where [tex]p^2[/tex] represents the frequency of the homozygous dominant allele, [tex]2pq[/tex] is the frequency of the heterozygous allele while q or[tex]q^2[/tex] represents the frequency of the homozygous recessive allele.
