A Matter of selection

1. The Leaves seem to exhibit the most variation because some are small some are big. and they have many different shapes, sizes, feels and colors. The leaves have different measurements including one that is 271/2 CM long and 18 1/2 CM wide. Another might be 20 CM long and 131/2 CM wide. One more would be 19 1/2 CM long and 27 CM WIDE. The greatest range of variations is in the stems because they are what contribute to the growth of the pants and leaves. Calculations for the stems are 30 Cm long, 25 CM long and 29 CM long.  the average length of the leaves is 20 Cm Long and 13 plus CM wide. the average length of of the stem is 29 CM long.
2. I think they have different traits due to their different parents. the plants that have the same traits or almost the same traits may have been a part of selective breeding. this kind of breeding is also called artificial selection. size and look depend on the different genes a plant was given. the traits that the plants have may have been passed down from their parents in a process called descendant with modification. some plants may be missing a few traits that their parents have. this is called natural variation, this happens when genes are copied and traits of the parents are sightly changed and their features sometimes come out different on their children. natural variation is another word for natural variation because it is the change in DNA sequence
3. The flowers of the Brassica seem to be the most consistently the same. they're colors are all yellow and the stems are all green. they are difficult to tell one from another  just looking at them. The average height of the flower petals is 3 cm long. Most of them looked exactly the same. The reason they are the almost exactly the same is due not only to their parents and ancestors but selective breeding. In selective breeding most of the traits that are passed down from their parents and ancestors are not all shown in the phenotype. What is shown is a balance of both ancestor traits and the traits they were given by the the other breed they were breaded with. The traits that a plant has are decided by the person that breeds them. So therefore, breeders select whichever breeds and traits they want their plants to have.
4. In order for these plants to look a lot different, plant breeders would have to breed the flowers with another one that is long and the petals are big. since the petals are about 3 cm long form petal to stem in order for the flower to come out different they would have to be breeded with another flower or plant that that has long petals. In looking for a flower to breed it with the breeder might look for a flower that has a slightly different color.
