|
It prevents a high mutation rate.
|
|
|
It reduces the risk of extinction due to environmental change.
|
|
|
It can only occur if the species population size is already large.
|
|
|
It allows the species to use a variety of strategies to avoid predation.

Detailed explanation-1: -Maintaining high genetic diversity allows species to adapt to future environmental changes and avoid inbreeding. Inbreeding, which happens when there are small, isolated populations, can reduce a species’ ability to survive and reproduce.
Detailed explanation-2: -A genetically diverse population of individuals is more likely to survive than a population of individuals with similar genetic makeup. Variation allows some individuals within a population to adapt to the changing environment and natural selection allows the expression of those beneficial traits to persist.
Detailed explanation-3: -Species with low genetic variability are generally at greater risk of extinction than the species with more genetic variability.
Detailed explanation-4: -Explanation: Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.
