What is the difference between the Bottleneck Effect and the Founder Effect?

The term Bottleneck Effect is used when a population has been reduced at some point in time to a small number of individuals with a loss of genetic diversity as a result. The population size may return but the bottleneck effect will be seen in the loss of genetic variation.
The Founder Effect also describes a population with a loss in genetic variation, however the cause is not associated a decrease on total population, but in a small part of the original population moving into a new habitat and becoming genetically isolated from the original population.

∙ 13y agoThese are two similar concepts. Both try to explain how new breeds or species can arise with no improvement on fitness, i.e. why there is so much "useless" variability in nature.
The two concept are so closely related that many consider that the founder effect is just another name for the acceleration of genetic drift as the population gets smaller.
The founder effect is related to the concept of pure breed. For example, dog breeders will prevent pure breed animals from mating outside of their breed; they create and artificially maintain a genetic bottleneck (another related concept).

Types of genetic drift?
Founder effect & Bottleneck effect.
What characteristic do a bottleneck and a founder effect have in common?
The founder effect a genetic bottleneck are similar in their effect on the genetic diversity of a local population in both situations. They result in the development of a population from a small number individuals and is likely to have reduced genetic diversity.
What is genic drift?
Genetic drift is change in allele frequencies due to random chance events. Two types are the Founder effect and the Bottleneck effect. The founder effect is when a subset of a population goes to a new are where there are no other of that same species. The bottleneck effect is when a large population is reduced to a small population. Genetic drift decreases variation in a population and has a greater effect on a smaller population than a larger one.
Which is an example of genetic drift?
Allele frequencies change randomly each generation. APEX
The number of trout in a lake drops when the lake is polluted. The trout population increases but the allele frequency is different than it was before the pollution. What type of effect is this?
Apex . . bottleneck

Founder effect & Bottleneck effect.
Bottleneck effect vs founder effect?
bottleneck effect is an evolutionary event in which population size is radically reduced because of catastrophic events. founder effect occur when few individuals migrate from main population and establishes a separate population in new geographical location. both of these are special cases of genetic drift.
