Assignment #9: A matter of selection

     The traits I will be measuring and recording are the height of the plants. I chose to do this because height varies from the genes  different types of plants even within the same species. Study the plants  observations there has been a wide range of heights. I will be specifically be looking at the Brassica (cabbage), the Broccoli and my plant, the Kohlrabi. The shortest coming in at 10 inches is the Brassica. Then at the tallest is 40 inches which is the Broccoli. In between is the Kohlrabi at 16 inches. The difference between the tallest and shortest is 30 whole inches! This represent the vast majority of heights between species because of the environments and how fast their mutations are. Though some farmers and food processors have done selective breeding to either largen and or fasten the growth rate of their plants. This process is known as artificial breeding. The breeding of plants to get desirable traits to stop natural variations. The most similar feature of all the plants would be their leaves. They were mostly around the same color and lengths. All were a darker shade of green.Plant breeders would breed together specific plants together.  They would pick the plants with the perfect leaves so those features pass on to the offspring giving them that characteristic.  THey would do this over and over to get the perfect color of leaves.
