A scientist observes a population of cheetahs on the plains in southern Africa and noticed that cheetahs have very little genetic variation. The scientists claims that the cheetahs are susceptible to extinction as a result of climate change. 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

Disaster effect, because the cheetahs have mutated to produce ineffective proteins

Frameshift mutation, because it only produces ineffective proteins

Substitution mutation, because the these mutations cannot be passed to offspring

The bottleneck effect refers to a reduction in the size of a population, which leads to a decrease in genetic variation. In the case of cheetahs, the limited genetic variation makes them more susceptible to extinction because if one cheetah is affected by environmental stresses, such as climate change, it is likely that all the cheetahs in the population will be susceptible to the same stressors. This lack of genetic diversity reduces their ability to adapt and survive under changing environmental conditions.
