How is a gene pool and biological evolution related?

WebGenetic drift is a change in the gene pool of a small population due to chance and results from a drastic reduction in population size. Passing through a bottleneck, " a severe reduction in population size, decreases the overall genetic variability in a population because at least some alleles are lost from the gene pool and results in a ... WebGenetic drift, also known as allelic drift or the Wright effect, is the change in the frequency of an existing gene variant in a population due to random chance.. Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed.

WebGenetic drift When the beetles reproduced, just by random luck more brown genes than green genes ended up in the offspring. Natural selection Beetles with brown genes escaped predation and survived to reproduce more frequently than beetles with green genes, so that more brown genes got into the next generation.

WebGene flow — also called migration — is any movement of individuals, and/or the genetic material they carry, from one population to another. Gene flow includes lots of different kinds of events, such as pollen being blown to a new destination or people moving to new cities or countries.

WebGenetic drift occurs because the alleles in an offspring generation are a random sample of the alleles in the parent generation. Alleles may or may not make it into the next generation due to chance events including mortality of an individual, events affecting finding a mate, and even the events affecting which gametes end up in fertilizations.
