An example of genetic drift is when a small group of individuals from a population colonize a new area, leading to a reduction in genetic diversity due to the limited number of individuals contributing to the gene pool. Over time, this can result in certain traits becoming more common simply by chance, even if they do not provide a specific advantage for survival.

Random Chance
Gene frequencies in a gene pool may shift randomly and by chance This is called?
Genetic drift. It refers to the random fluctuation of gene frequencies in a population due to chance events, particularly in small populations. It can lead to the loss of genetic diversity and the fixation of certain alleles over time.
What are the changes of allele frequency in a small population that is due to random chance and don't follow the laws of probability?
Random changes in allele frequency are due to genetic drift.
What is the Random change in a populations allele frequency is known?
Genetic drift is the random change in allele frequencies in a population. It is caused by chance events and has more pronounced effects in small populations where genetic diversity is lower. Over time, genetic drift can lead to the loss of certain alleles or fixation of others in a population.
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.
Is genetic drift an example of macroevolution?
No, genetic drift is an example of microevolution.
What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
People with one sickle cell are not likely to get malaria what is this an example of?
Genetic drift
People with one sickle cell allele are not likely to get malaria. What is this an example of?
Genetic drift
Which of the following events do biologists consider a random change?
you do not provide any choices, so it is impossible to answer your question as stated.
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.
What small genetic change such as a single mutation may result in?
genetic drift....
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.
Is the English peppered moth the example of random genetic drift?
The English Peppered Moth is a result of natural selection, not random genetic drift. This moth evolved because of the light colors of lichens on trees in their habitats.
What is an example of genetic drift APEX?
Random Chance
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.
What is genetic drift-?
Genetic drift is the random change in the frequency of alleles within a population's gene pool. It can cause the genetic composition of a population to change in one direction or another. Combined with natural selection, genetic drift is a principal force in biological evolution.Another Answer:Genetic drift is where random chance events which can effect the gene's abundance in a population, regardless of whether the gene is advantageous or not. For example, a natural disaster kills animals indiscriminately, regardless of their genetic makeup.
