One of the main reason of Genetic drift is MIGRATION.
Explanation:
- MIGRATION is simply the process of moving from one place to another.
- This causes the removal of a particular type of allele from that particular place.
-
In terms of Genetic Drift it is defined as the isolation of a group of species ,or genes from one place to another which result in the huge loss of that species or genes from that place.
-
This process of isolation may be due to several reasons:
(1)Threat of one type of species over other type which force the inferior type to isolate from that area.
(2)Due to weather conditions,etc. -
Migration can introduce new gene to a population or create separate genetic populations depending on which way the migration occurs.
- Separate genetic population will drift apart slowly as their gene pools are not intermixed so any new mutations or random changes in allele frequency will cause genetic drift.
