Conservation biologists studying cheetah populations have determined that the lack of genetic diversity among the cheetahs is due to genetic drift.

Which statement explains the most likely consequence of having a low genetic diversity on the cheetah population?

• The chances of a mutation occurring in the cheetah population are decreased, increasing the cheetah survival rate.

• The gene pool remains in equilibrium and future generations of cheetah offspring are stronger and better adapted to their environments.

• The cheetah population becomes less likely to survive an outbreak of a disease or an environmental change, increasing the chance of species extinction.

• Genetic variability is maintained from older cheetah populations that have survived and endured environmental stressors.
