|
|
The “p” represents the frequency of the recessive allele for a specific trait in a population.
|
|
|
In order to use the equation, you have to know all of the genotype frequencies first.
|
|
|
The equation allows you to discover the genotype frequencies if you know the phenotype frequencies.

Detailed explanation-1: -p2 + 2pq + q2 = 1 mathematically represents Hardy-Weinberg’s principle used to calculate the genetic variation of a population at equilibrium. It states that the allele frequencies in a population are stable and remain constant from one generation to another.
Detailed explanation-2: -The equation is an expression of the principle known as Hardy-Weinberg equilibrium, which states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
Detailed explanation-3: -Answer and Explanation: In the Hardy-Weinberg Theorem it states p2 +2pq + q2 = 1. p2 represents the frequency of the homozygous dominant genotype, q2 represents the frequency of the homozygous recessive genotype, and 2pq represents the frequency of the heterozygous genotype.
Detailed explanation-4: -The Hardy–Weinberg principle states that after one generation of random mating genotype frequencies will be p2, 2pq, and q2. In the absence of other evolutionary forces (such as natural selection), genotype frequencies are expected to remain constant and the population is said to be at Hardy–Weinberg equilibrium.
