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.

What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
Name the vocabulary term that describes the alteration of allelic frequencies by chance events alone?
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 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.
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.

Gene frequencies in a gene pool may shift randomly and by chance This is called?
Genetic drift. It refers to the random fluctuation of gene frequencies in a population due to chance events, particularly in small populations. It can lead to the loss of genetic diversity and the fixation of certain alleles over time.
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 are the changes of allele frequency in a small population that is due to random chance and don't follow the laws of probability?
Random changes in allele frequency are due to genetic drift.
How would genetic drift affect a population in genetic equilibrium?
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.
