A random chamnge in the frequency of a gene is called genetic drift.
There is disagreement about how much genetic drift occurs in nature, but it cannot be responsible for producing adaptations. Natural selection is the only known scientific mechanism for producing the adaptations which we see in all organisms.
A change in the frequency of a particular gene in one direction in a population is called genetic drift. Genetic drift refers to the random fluctuation of allele frequencies in a population over time, leading to a change in the genetic composition of the population.
Factors that can change the allele frequency of a population include natural selection, genetic drift, gene flow, mutations, and non-random mating. Natural selection favors certain alleles, genetic drift causes random changes, gene flow introduces new alleles, mutations create new variation, and non-random mating can lead to specific alleles being passed on more frequently.
A genetic drift is a random change in allele frequency over time that is brought about by chances. A bottle neck is a drastic reduction in population size brought about by severe pressure.
A change in the gene pool due to chance is genetic drift.
A mutation
A change in the frequency of a particular gene in one direction in a population is called genetic drift. Genetic drift refers to the random fluctuation of allele frequencies in a population over time, leading to a change in the genetic composition of the population.
In Hardy-Weinberg equilibrium, allele frequencies in a population remain constant from generation to generation. This means that the population is not evolving. Factors such as no mutation, no gene flow, random mating, large population size, and no natural selection contribute to Hardy-Weinberg equilibrium.
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.

The frequency of the populations alleles. Their gene frequency must change to have evolution.
Gene mutation causes the phenotype frequency in a population to change after each generation.
A genetic drift is a random change in allele frequency over time that is brought about by chances. A bottle neck is a drastic reduction in population size brought about by severe pressure.
The frequency of an allele in a gene pool is determined by counting the number of copies of that allele in a population. This frequency can change through evolutionary processes such as genetic drift, natural selection, mutation, and gene flow. Tracking allele frequencies helps scientists study population genetics and evolutionary dynamics.
Genetic drift is the random change in the frequency of alleles within a population's gene pool. It can cause the genetic composition of a population to change in one direction or another. Combined with natural selection, genetic drift is a principal force in biological evolution.Another Answer:Genetic drift is where random chance events which can effect the gene's abundance in a population, regardless of whether the gene is advantageous or not. For example, a natural disaster kills animals indiscriminately, regardless of their genetic makeup.
Not sure what you are asking, but, evolution is the change in allele frequency over time in a population of organisms.
Changes in the frequency of a gene within a population can lead to genetic variation. This can impact the traits expressed in individuals and influence the population's overall genetic diversity. Over time, changes in gene frequency can result in evolution and adaptation within a population.
The entire collection of genes among a population is called the "gene pool".
