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: [tex](p+q)^{2}[/tex] = [tex]p^{2}[/tex] + 2pq + [tex]q^{2}[/tex] = 1 where:
[tex]p^{2}[/tex] = is the frequency of genotype A1 A1 <- Homozygous
2pq = is the frequency of genotype A1 A2 <- Heterozygous
[tex]q^{2}[/tex] = is the frequency of genotype A2 A2 <- Homozygous
These frequencies are kept constant from generation to generation.
