During long periods geographically and genetically isolated, it is known for its unique flora and fauna.

The herd has remained remarkably genetically isolated for hundreds of years, surviving despite inbreeding depression due to the small population.

These groups branched off early in human history and have remained relatively genetically isolated since then.

On Vancouver Island, where the cougar population is genetically isolated, "we literally have a different breed of cat," he said.

The population remains genetically isolated, however, which is a cause of concern for some.

Both populations have been physically and genetically isolated since the last ice age (c. 12,000 yrs).

Instead, populations in different regions are distinct, and the farther apart any two hot springs, the more genetically isolated are their microbes.

When populations become genetically isolated, heritable variations may accumulate so that they become different from the parental population.

Geographically and genetically isolated, Tasmania is known for its unique flora and fauna.

This species consists of 14 "syngens", each genetically isolated from every other, and biochemically unique.
