Genetic drift is a stochastic process that acts by changing the allelic frequencies of species over time, founders effect and bottle neck effect are examples of this process.
It is a stochastic process that produces a change in the allele frequencies within the population, this means that they increase or decrease by chance.
The main genetic effects of a bottleneck are loss of genetic variability and the founder effect can cause traits to become fixed in a species that, in a larger population, never would.
Therefore, we can conclude that founders and bottleneck effects are one of the clearest causes of genetic drift mechanisms, along with resource limitations in a given environment.
