What is the main reason cauliflower, cabbage, and broccoli developed from wild cabbage?
Answer and explanation
Correct answer: Artificial selection
Artificial selection occurs when humans repeatedly choose and breed organisms that possess desired heritable traits. In wild cabbage, people selected different features, such as enlarged leaves, flower clusters, or stems, over many generations. This produced distinct cultivated forms including cabbage, cauliflower, and broccoli. A natural disaster, sex determination, or fossilisation does not create these selectively bred varieties, so option B is correct.
