the most genetic variation is i don't really care hoped it helps.. lol
a large population that has existed for a long period of time
(StudyIsland answer)
genetic drift may occur when a small group of individuals colonizes a new habitat.
A small population.
plants
Genetic Drift
In small, isolated populations.
No forces will act on the particles and the particles will drift apart. I don't know if im correct.
No, not all mutations are passed on to children. Mutations can occur in the DNA of reproductive cells (eggs and sperm) and if they are present in those cells, they can be passed on to the next generation. However, most mutations occur in non-reproductive cells and are not passed on to offspring.

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.
Victimization is most likely to occur when
Genetic drift usually only has effect on the genetic diversity of small populations of a species. Often times, genetic drift can greatly reduce the diversity of a population if a significant percent of members of the population leave by a chance event (as opposed to natural selection.) This means that their alleles for various genes leave with them. Genetic drift does not always effect genetic diversity. Most of the time, it is the allele frequency that is affected by genetic drift. For example, if there are 60 long-finned bass and 40 short-finned bass living in a pond, the gene frequency ratio is 3:2. If 25 short-finned are fished out, the allele frequency is now 4:1. If all or most of the members of a population carrying a specific gene were removed from the population because of genetic drift, that would effect the genetic diversity.
A stock split is most likely to occur when
no, they most likely occur wherever strong updrafts occur.
Genetic drift or allelic drift is the change in the frequency of a gene variant (allele) in a population due to random sampling.[1] The alleles in the offspring are a sample of those in the parents, and chance has a role in determining whether a given individual survives and reproduces. A population's allele frequency is the fraction of the copies of one gene that share a particular form.[2] Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation.When there are few copies of an allele, the effect of genetic drift is larger, and when there are many copies the effect is smaller. Vigorous debates occurred over the relative importance of natural selection versus neutral processes, including genetic drift. Ronald Fisher held the view that genetic drift plays at the most a minor role in evolution, and this remained the dominant view for several decades. In 1968 Motoo Kimura rekindled the debate with his neutral theory of molecular evolution, which claims that most instances where a genetic change spreads across a population (although not necessarily changes in phenotypes) are caused by genetic drift.
Which would most likely decrease the genetic variation in the human population?
