         1.The part of the Brassica Oleracea that seems to show the most difference would be the leaves, in their shapes, they are varied a lot between other types of Brassica Oleracea. An example of one of these variations of the leaves would be the cabbage, and the leaf size average of ratio is 1.64, compare this to the Kale leaf average of ratios which is 3.7  

2.There is so much variability in the domestic versions of Brassica oleracea because people are selective breeding to have the kinda plant they want.

3.The part of the Brassica oleracea plant that is the most consistent would be the flowers because they are all the same shape, color, and size. This is probably because of the selective breeding that humans have done over the years. Since, back in the day, they weren't searching for the look of the flower, they were searching for the best tasting Brassica oleracea plant

4.The plant breeders would need to think of a characteristic that they would like to be seen in that plant So, they have to find and choose parents that show the desired traits and breed them with each other. Then, they would take the best babys from the two parents and repeat the process until you want trait.
