Genetic drift tens to occur in populations that?
Genetic drift has a larger effect on smaller populations.
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.
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.

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?

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 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.
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.
When is gene drift a major factor in evolution?
Gene drift tends to be a major factor in evolution in small populations, where random fluctuations can have a larger impact. It is particularly important in cases of genetic bottleneck or founder effect, where a small group establishes a new population with reduced genetic diversity, leading to increased susceptibility to gene drift.
What statistical rule does genetic drift follow in small and large populations?
In small populations, genetic drift follows the rule that genetic variation can change quickly due to random sampling effects, which can lead to loss of alleles and increased genetic homogeneity. In large populations, genetic drift is less pronounced due to the dilution effect of larger sample sizes, which helps maintain higher levels of genetic diversity over generations.
