Genetic variation refers to the differences in genetic information between individuals of the same species. The level of genetic variation within a species can have significant implications for the survival and adaptability of that species.
If a species has low levels of genetic variation, it means that there is little diversity within the gene pool, making the species more vulnerable to diseases, environmental changes, and other threats. This is because there are fewer genetic options available for the species to adapt and evolve to changing conditions.
On the other hand, high levels of genetic variation allow for greater adaptability and resilience in the face of environmental challenges. This is because there are more genetic options available for the species to draw from and adapt to changing conditions.
Allows a species to evolve over time and adapt to changing environments. Without genetic variation, a species may not be able to survive long-term and may become extinct.
In summary, the level of genetic variation within a species is essential for its survival and adaptability. Low levels of genetic variation can make a species more vulnerable to threats, while high levels of genetic variation increase adaptability and resilience.
