founderevents
Founderevents are demographic processes in which a new population is established by a small number of individuals from a larger source population, leading to a founder effect. The small founding group carries only a subset of the source population’s genetic variation. As the new population grows, genetic drift can rapidly alter allele frequencies, potentially increasing or fixing alleles that were rare in the original population.
Founderevents are a form of bottleneck associated with colonization, migration, or geographic isolation. They differ from
Consequences of founderevents include reduced genetic diversity, increased linkage disequilibrium, and higher homozygosity. These changes can
Examples often cited in population genetics include historical colonizations such as island settlements (for instance, communities
Researchers study founderevents using genetic data, coalescent theory, and simulations to infer historical population sizes, migration,
