Genetic drift meaning simple
Webgenetic drift, also called genetic sampling error or Sewall Wright effect, a change in the gene pool of a small population that takes place strictly by chance. Genetic drift can result in genetic traits being lost from a population or becoming widespread in a … WebGenetic drift is a random change in allele frequencies within a population. It is one of the main mechanisms that drive evolution. Another effect of genetic drift occurs when species are divided into several different populations. In this situation, as the allele frequencies within one population shift due to genetic drift, the genetic ...

The change in frequency is … WebGenetic drift can also be magnified by natural or human-caused events, such as a disaster that randomly kills a large portion of the population, which is known as the bottleneck effect that results in a large portion of the gene pool suddenly being wiped out (Figure 11.8).In one fell swoop, the genetic structure of the survivors becomes the genetic structure of the …
