Well, think about it. Imagine the same amount of fluid in two different containers, one bottle, and one jam jar. Think about which will empty fastest if you turn them upside down. Bottleneck refers to anything that restricts flow. If you have a two-lane road that narrows to one lane, that's a bottleneck. If you have a walkway in a park that pass through a turnstile, that's a bottleneck too.

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.

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.


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.
