A road with a lot of traffic on such as a motorway and that has four lanes has two lanes closed and thus the traffic piles up as there are four lanes of traffic trying to fit through two lanes. Like pouring water out of a bottle. When you tip it upside down the water sloshes over to the neck of the bottle but piles up and takes time to drain from the bottle rather than a bucket where the water is drained instantaneously.

The sharp reduction of the gene pool and the numbers of a population through a severe epidemic is an example of?
the bottleneck effect
Which is an example of genetic drift?
Allele frequencies change randomly each generation. APEX
Types of genetic drift?
Founder effect & Bottleneck effect.
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
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.
A flood kills most of a population of ants that lives near a river. After the flood the ant population increases but its allele frequencies are different. What does this situation represent?
bottleneck (apex) [correct]
Genetic drift resulting from a disaster that drastically reduces population size is called?
The bottleneck effect.
When a few individuals start a new colony it most likely results in?
Extinction due to bottleneck effect
When few individuals start a new colony it most likely results?
Extinction due to the bottleneck effect.
Why does bottleneck effect happened in natural disasters?
Because natural disasters eliminate most of organisms which results in reduced population and bottle neck effect .
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 does bottleneck effect mean?
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.
