Genetic drift often occurs when there is a founder event because Because the founding population is usually composed of individuals with greater fitness (like strength) than individuals in the original population. Because the founding population is almost never a perfectly random sample of the original population. Because the founding population usually experiences high mortality during the founding event. Because the founding population usually experiences very different selection than the original population.

Concept explainers
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
