Question
In the laboratory setting, selection for a trait in fruit flies Blank______.Multiple choice question.has had mixed responses (as predicted for some traits but not for others)has consistently lead to a strong, predictable evolutionary responsehas never achieved a consistent, predictable evolutionary response
Solution 1
The correct answer is: has consistently lead to a strong, predictable evolutionary response.
In a laboratory setting, scientists have the ability to control the environment and breeding of fruit flies. This allows them to select for specific traits and observe the evolutionary response over multiple generations. The results have consistently shown a strong, predictable evolutionary response. This is because the traits that are being selected for become more common in each successive generation, demonstrating the principle of natural selection.
Solution 2
The correct answer is: has consistently lead to a strong, predictable evolutionary response.
This is because in a controlled laboratory setting, scientists can manipulate the environment and breeding to select for specific traits in fruit flies. Over time, this leads to a consistent and predictable evolutionary response as those traits become more common in the population.
