Genetic diversity is important because it protects species from
extinction or dangerous bottle necks. If a species has low genetic
diversity, it is much more vulnerable to the devastating effects of
disease and infection. Genetic diversity allows some individuals in a
population to have genetic variations that make them naturally resistant
to a given threat. Thus, these individuals are able to procreate and
continue the species. Without genetic diversity, a species would be
incapable of adapting to long term environmental conditions such as
climate change, predation and infection.
