Write the difference between broccoli and …

In its uncultivated form, <i>Brassica oleracea</i> is known as wild cabbage. The family includes cabbage, kale, collards, cauliflower, broccoli, kohlrabi, and brussels sprouts, each variety is chosen for certain traits like flower buds, large leaves, and edible stems. Artificial selection is a process in which humans consciously select for or against particular features in organisms. Artificial selection has enabled the cultivation of new crops with desirable traits from one single common ancestor. Furthermore, once a plant with the combination of alleles for a desired phenotype is produced, it can be propagated asexually by taking cuttings, grafting and encouraging runners or through layering. By artificial selection, man has produced many crop plants like broccoli, cabbage, cauliflower, kohlrabi etc. from a common wild cabbage species by selective breeding and artificial selection.
