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
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
Bottleneck effect, because environmental stresses affecting one cheetah could affect them all
Bottleneck effect, because environmental stresses affecting one cheetah could affect them all
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.**
The bottleneck effect refers to a sharp reduction in the size of a population due to environmental events or other pressures, leading to decreased genetic variation. This reduced genetic diversity can make the population more vulnerable to diseases and environmental changes, as there is less genetic variation for natural selection to act upon.
