Genetic diversity in a given population can be reduced in what is known as a "founder event" This is when a small group of people splits off from a larger population, leading to a smaller gene pool in the isolated group.

Here's a look at some of the most genetically isolated groups of modern humans.

Many Antioqueños carry a rare genetic mutation that leads to cognitive impairment by age 45 and AD by age 50 .

Half of the 8 million Ashkenazi Jews living today can trace their maternal lineage to just four original groups.

Finns created a database, called Finnish Disease Heritage , catalogues dozens of recessive genetic disorders commonly seen in ethnic Finns .
