No. Population bottleneck refers to a period in which the size of a population becomes much reduced, thereby reducing the number of alleles in the gene pool - and thus genetic diversity.

Natural selection requires that individuals in a population are?
Natural selection requires that individuals in a population are
Why would natural selection not occur in this poplutation?
What population? Perhaps you mean if there were no variation for natural selection to select from.
Which type of natural selection in which the mean characteristics of a population are preserved?
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
Natural selection acts on variation by?
Natural selection acts on variation by picking out from a population's gene pool those that are more fit to survive. More variation leads to more natural selection. For example, currently endangered cheetas are found out to have less genetic variation than other animals. As a result, if a disatrouous event occured, there are no genes that could help the cheetas survived. Thus, natural selection prevent the cheetas from reproducing as a population and they become extinct.
How does environmental pressure affect natural selection?
When nothing happens to exert strong population pressure on that population, natural selection favors the allele frequency already present. When mutations cause new traits, natural selection weeds these traits out because they're not as efficient as the others.
Is natural selection an example of macroevolution?
No, natural selection is the mechanism that drivesevolution.
Does natural selection work on preexisting variation in a population?
Natural selection does work on preexisting variations in a population. This is how the population was shaped to be the way that they currently are or were.
The lizard population changes into 80 percent dark-colored lizards and 20 percent light-colored lizards What is this an example of?
natural selection study island sucks.
How is a population different after it has experienced natural selection?
A population is different after natural selection because some of the negative genes have been weeded out. By experiencing natural selection things like obesity, weakness, and disease will be cut from the genetic pool (after many generations of coarse). Take a look at the Nam family to get a good example of this.
Natural selection requires that individuals in a population are?
Natural selection requires that individuals in a population are
Is it possible for a population to undergo natural selection?
No, there is no genetic variation upon which natural selection can operate.
Why does bottleneck effect happened in natural disasters?
Because natural disasters eliminate most of organisms which results in reduced population and bottle neck effect .
Why would natural selection not occur in this poplutation?
What population? Perhaps you mean if there were no variation for natural selection to select from.
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
Is a frog an example of natural selection?
no
Which type of natural selection favors average individual in a population?
It is stabilizing selection
Which type of natural selection in which the mean characteristics of a population are preserved?
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
