Answer 1

$\bold{\huge{\red{Genetic \: Drift}}}$

❄❄❄❄❄❄❄❄❄❄❄

Any change, either directed or undirected in a gene frequency in a population or the process of change in the genetic composition of a population due to chance or random events rather than by natural selection. It is one of the major forces of evolution. It can lead to the origin of new species. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time.

There are two major types of genetic drift: population bottlenecks and the founder effect. A population bottleneck is when a population's size becomes very small very quickly. This is usually due to a catastrophic environmental event, hunting a species to near extinction, or habitat destruction.
