Hardy-Weinberg Principle.
Le Chatelier's Principle. This principle states that when a system in equilibrium is subjected to a change, it will adjust to counteract the change and restore equilibrium.
Hardy and Weinberg wanted to answer the question of how genetic variation is maintained in a population over time. They developed the Hardy-Weinberg equilibrium principle, which describes the expected frequencies of alleles in a population that is not undergoing any evolutionary changes.
That situation is called a Hardy-Weinberg equilibrium. Not actually seen outside of the lab.
The Hardy-Weinberg principle is used in population genetics to describe the genetic variation of a population at equilibrium. It provides a mathematical model that predicts the frequencies of alleles and genotypes in a population, assuming no evolutionary forces are acting on it, such as selection, mutation, migration, or genetic drift. This principle helps researchers understand how evolutionary processes affect genetic diversity and can serve as a baseline for measuring changes in populations over time.
Genetic drift can disrupt genetic equilibrium by causing random fluctuations in allele frequencies within a population. Over time, genetic drift can lead to the loss of alleles, reduced genetic diversity, and potential changes in the population's genetic composition, deviating it from equilibrium.
The genetic equilibrium of a population can be disturbed by mutation, gene flow, genetic drift, and natural selection.
Le Chatelier's principle states that a system at equilibrium will respond to a disturbance by shifting its equilibrium position in a way that minimizes the effect of the disturbance. This means if you change the conditions of a reaction at equilibrium, the system will adjust to counteract that change and establish a new equilibrium.
Migration can introduce new genes into a population and increase genetic diversity, thus potentially disrupting the genetic equilibrium. If individuals from a different population arrive and interbreed with the local population, they can alter allele frequencies and introduce new variations. Over time, this can impact the gene pool and change the genetic equilibrium of the population.
genetic drift
It is true.
According to the Hardy-Weinberg principle, the frequency of alleles in a population will remain constant from generation to generation as long as equilibrium is maintained through random mating, no gene flow, no genetic drift, no natural selection, and no mutations.
Yes, this is the principle of Le Chatelier.
