a population bottleneck is often caused by _______.\n\no colonization of a new habitat\no new mutations that arise in a population\no introduction of individuals from a different population\no a natural disaster
Answer
Brief Explanations:
A population bottleneck occurs when a population's size is suddenly and drastically reduced. Natural disasters like earthquakes, floods, or wild - fires can cause significant mortality in a population, leading to a bottleneck. Colonization of a new habitat can lead to founder effects, new mutations are not the main cause of bottlenecks, and introduction of individuals from another population can increase genetic diversity rather than cause a bottleneck.
Answer:
a natural disaster
