Detailed explanation-1: -The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
Detailed explanation-2: -When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations. There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.
Detailed explanation-3: -The Hardy-Weinberg Equilibrium (HWE) is an important fundamental principal of population genetics, which states that “genotype frequencies in a population remain constant between generations in the absence of disturbance by outside factors” (Edwards, 2008).
