The simple definition of genetic drift ( also referred to as Sewall Wright effect or allelic drift ) is a method of changing the population’s frequency of an allele by chance where some individuals with specifi

founder effectgenetic driftselectionmutationsRare genetic diseases have been reported with high frequency in some populations. The mechanisms which were proposed to explain most of these observations include founder effect, genetic drift or selective advantage. In recent years, many genes have been ...

Random genetic drift accompanies such founder effect, to severely reduce the genetic variation that exists in the original population. In the new population, the founder effect can rapidly increase the frequency of an allele whose frequency was very low in the original population. If the allele is...

Also, genetic drift can affect genetic variability in a population as well. An example of this would be the “founder effect” and the “bottleneck effect”. The founder effect is when a group of individuals become isolated from a large population, this can cause a change in allele frequencie...
