Meaning and definition of bottleneck effect : Genetic drift resulting from the reduction of a population, typically by a natural disaster, such that the surviving population is no longer genetically representative of the original population.
A founder effect occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have: 1  reduced genetic variation from the original population.2  a non-random sample of the genes in the original population.ottlenecks and Founder Effects. Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a populations size is reduced for at least one generation.
