Final answer:
A bottle neck scenario refers to a situation in which a small portion of a population survives a catastrophic event or other selection pressure, causing a significant reduction in genetic diversity. One example of a bottle neck scenario is the Achromatopsia disorder, which is a rare genetic condition that results in complete color blindness.
Step-by-step explanation:
A bottle neck scenario refers to a situation in which a small portion of a population survives a catastrophic event or other selection pressure, causing a significant reduction in genetic diversity. One example of a bottle neck scenario is the Achromatopsia disorder. Achromatopsia is a rare genetic condition that results in complete color blindness. The disorder is caused by a mutation in the genes responsible for the production of cone cells in the retina. As a result, individuals with Achromatopsia have a reduced ability to perceive color and rely on monocular cues for depth perception.
