Question

What is genetic drift ? How it works ? ​

Answer 1

GENETIC DRIFT:-When the frequency of some genes gets changed in a small population due to some accidental reasons, such phenomenon is known as Genetic Drift. Genetic drift can give rise to different changes in sub-populations. It is random and rarely produces adaptations to the environment.

Answer 2

Genetic drift is a process in which allele frequencies within a population change by chance alone as a result of sampling error from generation to generation. Genetic drift is a random process that can lead to large changes in populations over a short period of time.
