After a bottleneck event the population of rabbits in an area has significantly decreased a decade later the population of rabbits recovers to its original numbers which statement is correct about the rabbits the rabbits?
They are less likely to survive environmental changes because of the bottleneck event.
They are more likely to survive environmental changes because of the bottleneck event.
They are as likely to survive environmental changes because they survive the bottleneck event.
They are as likely to survive environmental changes because their population has recovered.
I think they are less likely to survive but that's just my guess so I might be wrong.
The correct statement is: They are as likely to survive environmental changes because their population has recovered.
The correct statement is:
They are more likely to survive environmental changes because of the bottleneck event.
Explanation:
A bottleneck event refers to a significant decrease in the population of a species. This often happens when there is a drastic reduction in the available resources or a major change in the environment. During a bottleneck event, the population experiences a decrease in genetic diversity as only a small portion of the original population survives.
The reduction in genetic diversity can actually make a population more prone to the negative effects of environmental changes. Changes in the environment, such as new predators or diseases, might have a greater impact on the population since there is less genetic variation to adapt to these changes.
However, in this scenario, the question states that a decade later, the rabbit population has recovered to its original numbers. This means that the population has experienced a period of growth, allowing new genetic variation to emerge. The recovery of the population can increase genetic diversity, which is beneficial for the rabbits' ability to adapt to environmental changes.
Therefore, the statement "They are more likely to survive environmental changes because of the bottleneck event" is correct, accounting for the increased genetic diversity resulting from the population's recovery.
