Founder effect
From ISOGG Wiki
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. In some cases, the founder effect plays a role in the emergence of new species.
The term genetic drift is also used. Many people regard the two terms as synonymous.
