Question

Genetic Drift occurs due to :

A

Natural selection

B

Sudden population migration

C

Continuous gene migration

D

Mutation

Step-by-Step Solution

when migration of a section of a population to another place occurs, gene frequencies change. If this migration happens multiple times, it is termed 'gene flow' (or continuous gene migration). However, if the change in allele frequency occurs by chance (which can happen during a sudden isolation or migration of a small group, known as the founder effect), it is called genetic drift , . Therefore, sudden population migration is associated with genetic drift, whereas continuous migration is gene flow.

Exam Context & Concepts Covered
