founder effect
This term is a specialized technical expression used in population genetics. It describes a specific type of genetic drift where a small group breaks away from a larger population to establish a new colony, carrying only a fraction of the original genetic diversity. This often leads to an increased frequency of specific inherited traits or rare diseases within the new population.
In academic and scientific writing, it is used as a precise mechanism to explain biological anomalies in isolated groups. It should not be confused with the bottleneck effect, which involves a drastic reduction in population size due to an environmental disaster rather than the migration of a small subgroup.
