What else can I help you with?
When a small population separates from a larger population the allele frequencies change between the two populations. Which is event is most likely to occur from such frequent changes?
Genetic drift is likely to occur when a small population separates from a larger population. This is because genetic drift is the random change in allele frequencies that happens in small populations due to chance events. Over time, these changes can lead to genetic divergence between the two populations.
What kinds of populations are affected by genetic drift?
Genetic drift occurs in all finite populations. However the effects of drift are more pronounced in smaller populations than in large ones. Meanwhile, even though they are more present in smaller populations, the drifting is more likely to occur in larger populations because of the larger number of different genetic combinations present. Throughout evolution of populations, genetic drifting effects all types of population sizes, though it is more likely in larger populations but more present in smaller populations.
When is crossing over most likely to occur?
when you die
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.
One consequence of genetic drift is?
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.
What is genetic drift most likely to occur in?
Genetic drift is most likely to occur in small populations where random events can have a greater impact on allele frequencies. It is also more common in isolated populations with limited gene flow from other populations.
Which factor would most likely disrupt genetic equilibrium in a large population?
Genetic Drift

What phenotype frequency in a population changes after each generation which would most likely be causing this?
Genetic drift, natural selection, and gene flow are factors that can cause changes in phenotype frequency within a population after each generation. These changes occur as a result of random chance events, differential survival and reproduction of individuals, and the introduction of new genetic material from outside sources, respectively.
