Genetic drift is a product of random sampling. Like all forms of sampling or selection, variation within the sample set is required. Thus for genetic drift to occur genetic change (mutation) is required. However, it would be an error to call genetic drift a product of genetic change.

What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
Is genetic drift an adaptive change?
Genetic drift is considered a form of evolution. If a single population is split into two isolated groups then genetic drift will result in increasing differences over time. Eventually they will become two different species, unable to interbreed even if the two groups are brought back together.
What is the similarity between natural selection and genetic drift?
No. Genetic mutations lead to changes in the gene. This results in a (possible) new allele. Genetic drift is the change in frequency of an allele in the population due to chance. The smaller the population the bigger the chance on genetic drift (like it is more likely to coin flip 10 heads in a row then 1000 heads) while on the other hand the bigger the population the bigger the chance new alleles will be created by mutations.
What is genetic drift-?
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.
Genetic drift tens to occur in populations that?
Genetic drift has a larger effect on smaller populations.
What small genetic change such as a single mutation may result in?
genetic drift....
A random change in a population's allele frequency?
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
What is the Random change in a populations allele frequency is known?
Random change in allele frequency is called genetic drift.
What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
Species drift to form a new species?
I think you mean genetic drift. Genetic drift is not strong enough in itself to cause speciation generally. Genetic drift is merely a sampling error in allele frequency change due to random events.
A change in a population gene pool due to a chance event?
The sudden change in the genetic make up or genetic form of an individual is called gene mutation.
What effect does genetic drift have on organisms?
Genetic Drift (or allelic drift) is the pseudo-random chance that a minor genetic change will eventually become a fixed genetic inheritance in a specific organism. IT is the underlying principal in the theory of evolution. There are many equations and probabilities involved, but the basic explanation is that as the number of generations with the genetic change increases, so does the chance that the change will become the norm, rather than the aberration.
Is genetic drift an adaptive change?
Genetic drift is considered a form of evolution. If a single population is split into two isolated groups then genetic drift will result in increasing differences over time. Eventually they will become two different species, unable to interbreed even if the two groups are brought back together.
Which of the following events do biologists consider a random change?
you do not provide any choices, so it is impossible to answer your question as stated.
The change in allele frequency?
Random change in allele frequency is called genetic drift.
A small genetic change such as a single mutation may result in what?
genetic drift....
