A matter of selection Marco

1. Which part (anatomy) or characteristic of the Brassica oleracea plants seems to exhibit the most variation (greatest number of different forms)? Which part or characteristic of the Brassica oleracea plants seems to show the greatest range of variation (biggest difference between one extreme and its opposite)? Use and include data collected from multiple measurements to support your answer.

          When I was observing the Brassica oleracea I noticed that the anatomy of the plants varied them most on the leafs of the plant.  The biggest difference was the shape of the leafs some were round while other plants had a little curve in the leaves.  The plant with the most different leafs was the kale it was sorta wrinkly and the edges looked like they had been cut up.  The texture was also very different in all the plants some were rubberlike while others were sorta soft like but all them had a protective layer  on it which repealed water.

2. Using the terms that follow, explain why you think there is so much variability in the domestic forms of Brassica oleracea: traits, selective breeding, artificial selection, genes, descent with modification, natural variations, mutations

          There is so much variation in the plants because only some of the traits get passed down to the plants offs spring so no two plants will be exactly the same.  There is also selective breeding and the plants can breed with the healthiest plant so then their off spring have a high chance of serving.  The plants also use artificial selection because the plants breed with each other.  Each plant has different genes so then it is possible for them to survive.  The plants also have different variations from natural variations and this is because the plant gets traits from the mother and the father.  Finally the plant uses mutations to help the plants live longer.

3. Which part (anatomy) of the Brassica oleracea plants seems to be most consistently the same in all of the examples in our garden, regardless of how extreme the differences between other parts of the same plants may be? Why do think this is so? Again, use and include data collected from multiple measurements to support your answer.

One of the things on the plant that has common anatomy is the size of the plants.  Each leave was about 11-15 inches.  I think they are close in the same size because the plants may have a common ancestor that passes the leaf size trait down.

4. What would plant breeders have to do in order to get the body part or characteristic you described above (in your response to question #3) to become much different than it is presently?

The plant breeder could take pollen from 2 different plants and put the different pollens on each plant and see if any of the plants have a fertile off spring and if one of them has a fertilize off spring keep Breading utile you can bead the plants
