Summary Introduction
Introduction:
The genetic drift can be defined as the variation in the relative frequencies of the alleles. This generally occurs in the small population, which may result in the disappearance of the alleles. The founder effect is a type of genetic drift resulting due to the separation of a small population from a large population.
