Abstract In this project, we wanted to see how artificial selection could be used to select which traits were present in the offspring of future plant generations. To observe this, we developed a test in which we used Brassica rapa , or fast growing plants. We transferred pollen between a population of short plants and did so again in a population of tall plants. We planted the produced seeds and grew a second generation of plants. The results showed that when short plants were bred with short plants, the offspring had a smaller mean length. The offspring produced when tall plants bred with tall plants had a larger mean length. 3

Introduction Evolution is mostly controlled by natural selection. Organisms with better traits suited to their environment will result in increased reproductive success and allow those traits to be passed on to the next generation, (Pg. S17, AP BIOLOGY INVESTIGATIVE LABS: An Inquiry-Based Approach) . Environmental factors are what determine which organisms will survive and produce the most offspring. In artificial selection, humans determine which organisms reproduce. This has the potential to select which specific traits are wanted or needed. The purpose of this project was to discover how artificial selection could be used to select which traits were present in the offspring of the next generation. How will the offspring be characterized if we chose to breed short plants with short plants and tall plants with tall plants?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
