Detailed explanation-1: -Founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals arising from a larger population.

Detailed explanation-2: -The founder effect is the reduction in genetic variation that results when a small subset of a large population is used to establish a new colony. The new population may be very different from the original population, both in terms of its genotypes and phenotypes.

Detailed explanation-3: -Definition. A founder effect, as related to genetics, refers to the reduction in genomic variability that occurs when a small group of individuals becomes separated from a larger population.

Detailed explanation-4: -In humans the founder effect is defined as a decrease of genetic variation in the population due to a population bottleneck followed by random genetic drift.

Detailed explanation-5: -The difference between founder events and population bottlenecks is the type of event that causes them. A founder event occurs when a small group of individuals is separated from the Page 3 rest of the population, whereas a bottleneck effect occurs when most of the population is destroyed.
