Type A viruses undergo both antigenic drift and shift and are the only flu … WebGenetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a population's size is reduced for at least one generation. Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population's genetic variation by a lot, even if the bottleneck cities in north carolina stateWebTypically, genetic drift occurs in small populations, where infrequently occurring alleles face a greater chance of being lost.

"WebApr 12, 2024 · Genetic drift and natural selection are two fundamental mechanisms of evolution that shape the genetic makeup of populations over time. While both processes involve changes in the frequency of alleles in a population, they differ in their underlying mechanisms, outcomes, and effects on genetic diversity. In this answer, we will explore … " - Genetic drift occurs due to

WebGenetic drift occurs via the when the founding members of a new population have different allele frequencies than the original population. . A sudden decrease in population size due to a disaster or other environmental factor can cause some alleles to become more prevalent and some alleles to disappear completely.

It leads to random changes in allele frequencies. Drift causes fixation of alleles through the loss of alleles or genotypes. Drift can lead to the fixation or loss of entire genotypes in clonal (asexual) organisms.
