What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
Which factor would most likely disrupt genetic equilibrium in a large population?
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.

Genetic drift is most likely to occur in?
small populations
Which factor would most likely disrupt genetic equilibrium in a large population?
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....
What type of population is most susceptible to loss of genetic variability as a result of genetic drift?
small populations
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.

Genetic drift tens to occur in populations that?
Genetic drift has a larger effect on smaller populations.
Does genetic drift lead to evolution?
Yes. Genetic drift-- the change in allelic frequencies of a population due to chance-- can play a major role in evolution. The effects of drift are most pronounced in small, isolated populations. Drift can bring alleles to fixation very quickly in such populations, and can lead to genetic differentiation between them, possibly contributing to speciation.
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.
