bottleneck effect is an evolutionary event in which population size is radically reduced because of catastrophic events. founder effect occur when few individuals migrate from main population and establishes a separate population in new geographical location. both of these are special cases of genetic drift.
Genetic drift. It is when a representative sample of emigrant alleles that break off from a larger population and travel to a new location do not represent a complete frequency of the parent populations alleles. They then vary from a little to greatly from the parent population. Deleterious recessive alleles can be expressed in this founder population in greater frequency sometimes. Look up the ' Quebec effect.
