This is also known as the allergic drift is defined as the change in the frequency of the existing gene, that directly or indirectly affects its ability to reproduce. As its random alteration of the genome of population.
This genetic drift may cause the species to die out or mutations in the formation of genes another aspect of this is the natural selection in which one species adapt to their respected environments.
There are chances that random statistical effects can occur in the isolated strategic pool as it has been one of the main factors of migration over time and has several disadvantages as compared to the process of natural selection.
