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)

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

Bottleneck effect, because environmental stresses affecting one cheetah could affect them all

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

O Frameshift mutation, because it only produces ineffective proteins

O

O

Answer 1

Bottleneck effect, because low genetic variation means the population may lack alleles needed to survive new diseases or environmental changes, so a single stress could impact most individuals.
