The founder effect and the bottleneck effect are cases in which a small population is formed from a larger population. These “sampled” populations often do not represent the genetic diversity of the original population, and their small size means they may experience strong drift for generations.

Explanation:

Bottlenecks and founder effects. Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a population's size is reduced for at least one generation. ... A founder effect occurs when a new colony is started by a few members of the original population.

Answer:

A bottleneck event severely reduces the fraction of a species able to pass on their genes to offspring. Any once rare recessive traits present in the surviving breeding population are passed to a larger fraction of the total population of offspring, thereby enriching those recessive traits in the total gene pool.
