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)ResponsesBottleneck effect, because environmental stresses affecting one cheetah could affect them allBottleneck effect, because environmental stresses affecting one cheetah could affect them allDisaster effect, because the cheetahs have mutated to produce ineffective proteinsDisaster effect, because the cheetahs have mutated to produce ineffective proteinsSubstitution mutation, because the these mutations cannot be passed to offspringSubstitution mutation, because the these mutations cannot be passed to offspringFrameshift mutation, because it only produces ineffective proteins

Answer 1

Bottleneck effect — because the population’s low genetic variation means they lack the diversity needed to adapt, so an environmental stress or disease that affects some individuals could threaten the whole population.
