Answer:
Frequency of recessive allele.
Step-by-step explanation:
The Hardy-Weinberg equation is represented as below:
p2 + 2 pq + q2 = 1
Here, p is the frequency of dominant allele while q denotes the frequency of the recessive allele. The "p2" refers to the frequency of dominant genotype in the population while "q2" is the frequency of recessive genotype in the population. Likewise, "2pq" represents the frequency of heterozygous genotypes in the population.
