Extinction vortex is the process that involves factors that aid in further shrinkage of small populations.It leads a small population towards extinction.

Two factors such as inbreeding and genetic drift, are engaged in driving the extinction vortex.

Reserves for conservation and protection of a population鈥檚 habitat would maintain genetic diversity and, consequently, biodiversity. Furthermore, the populace would need time to adjust to the new environment.

Thus, establishing reserves would maintain the population and existing genetic diversity but not rapidly increase the latter.

Therefore, the given statement is false.

Genetic diversity is the presence of different genetic characteristics due to variation in genetic information. It is measured both within a species and among other species populations.

Thus, introducing new individuals would introduce more genetic characteristics and introduce more diversity.

Therefore, the given statement is true.

Reduction in genetic diversity affects the fitness and reproductive ability of individuals in a population. Fitness and genetic diversity are correlated. Eliminating further individuals from a population would lower the genetic diversity.

Thus, least fit individuals arise due to loss of genetic diversity, and sterilizing them would further decline their genetic information and variety.

Therefore, the given statement is false.

The existing predation and competition keep a population in check and maintain ecological balance. However, over-predation and competition result in a decrease in the number of prey animals.

Controlling the population of predators and competitors would restore the prey population and genetic diversity, but it would require a substantial amount of time.

Thus, controlling the predator and competitor population would thereby restore genetic diversity gradually rather than rapidly.

Therefore, the given statement is false.
