Question:- 1. Brassica oleracea is the wild plant from which brussels sprouts, cabbage, broccoli, and cauliflower were domesticated. Why is it important to keep many diverse seeds from the forb B. oleracea across its range?   A. If our B. oleracea-derived crops are driven to extinction, we can re-domesticate them from the wild plant.   B. Our crop Brassicas are much more genetically diverse than B. oleracea because of extensive breeding programs, so we need to conserve as much of B. oleracea's diversity as possible.   C. The budding pattern in Brassica may be further modified to produce more productive crop plants.   D. B. oleracea may have gene variants that can be incorporated into our domesticated plants to increase their environmental range or tolerance to pests.   E. We may be able to domesticate another crop plant from B. oleracea.
