What does the example of different vegetables derived from wild cabbage show?
Answer and explanation
Correct answer: Artificial selection can produce many forms from one ancestor
Wild cabbage had heritable variation in different plant parts. Over generations, humans selected leaves, flower buds, stems or enlarged shoots according to their desired use. Continued selective breeding produced forms such as cabbage, cauliflower, broccoli and kohlrabi from a common ancestral stock. Therefore option A illustrates artificial selection and divergence of traits. The other options contradict genetics or the occurrence of evolution in plants.
