random changes in allele frequency (apex) [Correct]
No, genetic drift is an example of microevolution.
genetic drift....
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
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.
D) the change in frequencies of alleles due to random events
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 has a larger effect on smaller populations.
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.
Neutral drift, often referred to as genetic drift, is a mechanism of evolution that describes how allele frequencies in a population can change over time due to random sampling effects, rather than natural selection. This means that certain traits can become more or less common in a population purely by chance, especially in small populations where random events can have a significant impact. Neutral drift emphasizes that many genetic variations may not confer any advantage or disadvantage, leading to changes in genetic diversity over generations.
