Question
A population of cheetahs on the plains in southern Africa has very little genetic variation compared to other species in the area. Scientists are concerned that the cheetah population will not survive extreme environmental changes. What is the name of the effect the scientist observed and why is it a concern?(1 point)
Responses
Bottleneck effect, because environmental stresses affecting one cheetah could affect them all
Bottleneck effect, because environmental stresses affecting one cheetah could affect them all
Substitution mutation, because the these mutations cannot be passed to offspring
Substitution mutation, because the these mutations cannot be passed to offspring
Frameshift mutation, because it only produces ineffective proteins
Frameshift mutation, because it only produces ineffective proteins
Disaster effect, because the cheetahs have mutated to produce ineffective proteins

The correct response is:
**Bottleneck effect, because environmental stresses affecting one cheetah could affect them all.**
This effect refers to a significant reduction in the genetic diversity of a population, often due to a catastrophic event or environmental change that drastically reduces the population size. In the case of the cheetahs, the low genetic variation means that individuals may share similar vulnerabilities to diseases and environmental changes, which can compromise the population's ability to adapt and survive.
