According to the Hardy-Weinberg equilibrium principle, genotype and allele frequencies within a
population remain intrinsically constant from generation to generation. As a result, the Hardy-Weinberg
allele distribution can then be determined. If the allelic frequency measured in the field differs from the
predicted number, scientists can really determine which evolutionary factors are at work. However, the
population's genotypic frequency and allele frequency won't change unless some sort of evolutionary
force is affecting it. No mutation, random mating, no gene flow, an infinite population size, and no
selection are the five fundamental Hardy-Weinberg assumptions. Despite the fact that no population
can meet such requirements, the principle provides a helpful framework for comparing actual
population trends (OpenStax, 2016).
The five assumptions must all be true, in my opinion, for a population to be in Hardy-Weinberg
equilibrium because there are many populations that are not. The existence of all five of these
assumptions in a population is categorically impossible, and I don't believe a population can fulfill these
criteria. If there were no evolutionary pressures operating on the population, each generation would
have the exact same genetic makeup and gene pool, and these equations would always hold true, then
this would occur (OpenStax. 2016).
Natural selection and no mutation are the assumptions that I have chosen over others. Numerous
scientists and biologists agree that mutations are relatively common. For example, it is present in larger
species as well as bacteria and viruses. Furthermore, natural selection undoubtedly places
environmental pressure on species as they attempt to adapt to and survive conditions like rising
temperatures, excessive CO2, ocean acidification, greater UV rays, etc. (but only in terms of
temperature!). Another example would be the frequent and erratic swings in temperature. Another
common event that is likewise pretty straightforward is mutation. As I stated at the opening, I do not
think that many populations are in Hardy Weinberg equilibrium, but this theory does provide a highly
useful model as opposed to compiling actual population fluctuations for the equation they developed.
