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.

∙ 10y agoGenetic drift is a mechanism that changes species over time. This occurs when a random mutation occurs in one member of a species. They breed and preserve that trait. Eventually that trait is introduced into a larger portion of the population of that species.

What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
Is genetic drift of product of genetic change?
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.
Genetic drift tens to occur in populations that?
Genetic drift has a larger effect on smaller populations.
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 causes genetic drift?
random chance.
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 example of macroevolution?
No, genetic drift is an example of microevolution.
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.
Gene frequencies in a gene pool may shift randomly and by chance This is called?
Random changes.This would be called genetic drift.
Is genetic drift of product of genetic change?
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.
Genetic drift tens to occur in populations that?
Genetic drift has a larger effect on smaller populations.
How can a genetic drift be explained in biology?
A genetic drift is explained in biology as a gene variant changing frequency. Genetic drift can cause genes to disappear and not be passed onto the next generation.
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.
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.
When is genetic drift likely to occur?
genetic drift may occur when a small group of individuals colonizes a new habitat
What is relationship between blood groups and genetic drift?
Blood groups are affected by genetic drift randomly, making it special.
