Question

What do the variables in the Hardy-Weinberg equation represent?

Answer 1

This is the Hardy-Weinberg equation - p^2 +2pq + q^2 = 1

p^2 represents the frequency of the homozygous dominant genotype
q^2 stands for the frequency of the recessive genotype
2pq is the frequency of the heterozygous genotype

Hope this helps. :)

Answer 2

Answer:

The Hardy-Weinberg model is used to calculate genotypic frequencies based on allelic frequencies.

Explanation:

If the allelic pair A1 and A2 of any one locus is considered in a population,

p is the frequency of the allele A1 0 = <p = <1

q is the frequency of the allele A2 0 = <q = <1 and p + q = 1

Considering the same allelic frequencies for both sexes, for example, in men (p,q) and in women (p,q)

In the next generation you will have: $(p+q)^{2}$ = $p^{2}$ + 2pq + $q^{2}$ = 1 where:

$p^{2}$ = is the frequency of genotype A1 A1 <- Homozygous

2pq = is the frequency of genotype A1 A2 <- Heterozygous

$q^{2}$ = is the frequency of genotype A2 A2 <- Homozygous

These frequencies are kept constant from generation to generation.
