|
|
Genetic Drift |
Unpredictable fluctuations in allele frequencies from one generation to the next because of a population's finite size |
|
|
Bottleneck Effect |
Genetic drift resulting from the reduction of a population, typically by a natural disaster, such that the surviving population is no longer genetically representative of the original population |
|
|
Founder Effect |
Genetic drift that occurs when a few individuals become isolated from a larger population, with the result that the new population, with the result that the new population's gene pool is not reflective of the original population |
|
|
Gene Flow |
Genetic additions to or subtractions from a population resulting from the movement of fertile individuals or gametes |
