Which factor would most likely disrupt genetic equilibrium in a large population?
Genetic Drift
Where is genetic drift most noticeable?
In small, isolated populations.
Are all mutations passed on to your children?
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.
Which set of conditions would most likely cause a change in gene frequency in a sexually reproducing population?
A change in gene frequency in a sexually reproducing population is most likely caused by conditions such as natural selection, genetic drift, and gene flow. Natural selection can favor certain traits, leading to differential reproduction among individuals. Genetic drift can cause random changes in allele frequencies, especially in small populations. Additionally, gene flow, or the migration of individuals between populations, can introduce new alleles and alter gene frequencies.
When are behaviors most likely to occur?
REINFORCED
Genetic drift is most likely to occur in?
small populations where random events can have a significant impact on allele frequencies over time.
Which factor would most likely disrupt genetic equilibrium in a large population?
Genetic Drift
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.
Where is genetic drift most noticeable?
In small, isolated populations.
When is crossing over most likely to occur?
when you die
What type of population is most susceptible to loss of genetic variability as a result of genetic drift?
small populations

Victimization is most likely to occur when
When is a stock split most likely to occur?
A stock split is most likely to occur when
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.
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.
What will prevent genetic drift?
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.
