The Hardy-Weinberg equation is a mathematical expression that can be used to calculate the genetic variation of a population in equilibrium. 1908, H. Hardy and Wilhelm Weinberg independently describe the basic principles of population genetics and now name it the Hardy-Weinberg equation. This equation represents the principle called Hardy-Weinberg equilibrium, indicating that in the absence of interference factors, the amount of genetic variation within the population remains constant across generations.

In order to explore the Hardy - Weinberg equation, we can examine a simple locus with two alleles A and a. The Hardy Weinberg equation is expressed as follows.

Where p is the frequency of the "A" allele in the population and q is the frequency of the "a" allele. In this formula, p 2 represents the frequency of homozygous genotype AA, q 2 represents the frequency of homozygous genotype aa, and 2 pq represents the frequency of heterozygous genotype Aa. In addition, since the sum of the allele frequencies of all alleles at that locus must be 1, if p + q = p and q allele frequencies are known, Hardy-Weinberg is used to compare three genes You can calculate the frequency equation of the type. In population genetics studies, the Hardy-Weinberg equation can be used to determine if the frequency of genotypes observed in a population differs from the frequency predicted by the equation.

Hardy-Weinberg Equilibrium assumes that the allele frequency is constant over time. This equation does not assume genetic flow, mutation, natural selection, random mating, and large populations. The Hardy-Weinberg equation is used as a null hypothesis to determine if evolution took place in seeds. Intermittent equilibrium usually indicates a sudden change in the genetic pool of the species due to environmental disasters after the gene pool has not changed for a long time. The rise of mammals and the fall of reptiles and other living things proves this view.

Answer: Godfrey Hardy and Wilhelm Weinberg have formulated mathematical expressions to test whether genes within a population are affected by one of four evolutionary powers. Hardy Weinberg equilibrium is a set of ideal conditions where the gene is in equilibrium. Mutation, natural selection, gene flow or genetic drift did not occur. When these conditions are met, the allele frequency and genotype frequency will remain constant from generation to generation. If these conditions are not met and the genes are unbalanced, allele frequencies will change from generation to generation. Unbalanced genes may be affected by mutation, natural selection, gene flow or genetic drift
