Detailed explanation-1: -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-2: -There must be no mutation, no gene flow, a huge population size, random mating, and no natural selection for the Hardy-Weinberg equilibrium to persist.
Detailed explanation-3: -The Hardy-Weinberg Theorem deals with Mendelian genetics in the context of populations of diploid, sexually reproducing individuals. Given a set of assumptions (discussed below), this theorem states that: allele frequencies in a population will not change from generation to generation.
Detailed explanation-4: -The Hardy-Weinberg Law Allele frequencies remain constant over time because of the following: There is no appreciable rate of new mutation. Individuals with all genotypes are equally capable of mating and passing on their genes; that is, there is no selection against any particular genotype.
