Respuesta :
Option B is correct
Explanation:
The given situation is possible because of varietal selection and conventional breeding
- Varietal selection is the selection of varieties on fields of finished or near-finished products from plant breeding programmes
- Conventional breeding (classical breeding or traditional breeding), is the development of new varieties (cultivars) of plants by using older tools and natural processes, as opposed to the newer, more sophisticated and sometimes radical tools of molecular plant breeding
- There is a great diversity from single species of Brassica oleracea which has given many different types of vegetables
- Conventional breeding achieves it by crossing together plants with relevant characteristics, and selecting the offspring with the desired combination of characteristics, as a result of particular combinations of genes inherited from the two parents and deliver genetic crop improvement
Answer:
B.
Explanation:
As given here, the domestication of plants and subsequent breeding varieties has given rise to many different familiar crops. Through this, the single species of Brassica oleracea give different vegetables like: kale, cabbage, broccoli, cauliflower, kai-lan, brussels sprouts and kohlrabi, this is possible because of Varietal selection and conventional breeding.
