Explanation:
Genetic drift has a significant effect on small populations. Here, mutations accumulate in a population over time, altering the frequency of alleles or different forms of a gene. Natural selection can lead to a loss of variation in a population- referred to as genetic drift; the allelic frequency of one trait increases while others become less common. These variations typically occur due to mutation and recombination events.
∴Some variants or alleles can be lost from the population, becoming extinct.
Further Explanation:
During the process of cell division, spontaneous changes within the genome can arise, called mutations. These are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.
These mutations form variants which become stable within a population, leading to the formation of separate, genetically distinct populations called species.
Other phenomena further compound genetic drift...
