Definitions:

Founder Effect

A genetic phenomenon that occurs when a new population is established by a very small number of individuals, leading to significant genetic drift.

Allele Frequencies

The relative frequencies of all the different alleles of a gene in a given population.

Genetic Drift

The process in which allele frequencies within a population change randomly with no influence from selective pressures, often affecting smaller populations more significantly.

Genetic Variation

The diversity in gene frequencies within a population, which is the raw material for evolution.
