Genetic Drift: This represents random changes in small gene pools due to sampling errors in propagation of alleles. The bottleneck effect and founder effect are prime examples of genetic drift. In either case the number of individuals in a population is drastically reduced distorting the original allelic frequencies.

founder effect: random changes in allele frequencies resulting from establishment of a population by a very small number of individuals
bottleneck effect: refers to stressful periods that only few individuals of a once large population survive, resulting in substantially reduced genetic variation in the population

Founder effect is one of them. Now, look to your book for the other.
