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
Frameshift mutation, because it only produces ineffective proteins
Frameshift mutation, because it only produces ineffective proteins
Substitution mutation, because the these mutations cannot be passed to offspring
Substitution mutation, because the these mutations cannot be passed to offspring
Disaster effect, because the cheetahs have mutated to produce ineffective proteins
Disaster effect, because the cheetahs have mutated to produce ineffective proteins
Bottleneck effect, because environmental stresses affecting one cheetah could affect them all

The correct response is:
**Bottleneck effect, because environmental stresses affecting one cheetah could affect them all.**
The bottleneck effect refers to a significant reduction in genetic diversity that occurs when a population experiences a drastic reduction in size due to environmental events (like natural disasters) or human activities. This reduced genetic variation makes the population more vulnerable to diseases and environmental changes, as there are fewer genetic traits that might help some individuals survive.
