Fast Plants and Mendel’s Theories of Inheritance

Abstract
The “Brassica rapa” is a fast plant known as the field mustard. This plant is well known for its rapid growing rate, which makes it an easy breeding cycle and easy to pollinate. In giving so this makes “Brassica rapa” a great participant for testing Gregor Mendel’s theories of inheritance. The “Brassica rapa” acts like a test subject in testing cross-pollination giving the understanding to the dominant allele of colored stems. There are different colors that are visible on the stem that are above the soil; the colors vary from green to purple. P1 seed was ordered, germinated and cross-pollinated until germination of the next off spring of plants were also done. It was …show more content…

In the upper two thirds of the filter paper place 25 harvested seed in neat rows. Place the petri dish tilted on its end in a water reservoir, adding two centimeters of water. Place the dish and the water reservoir under the fluorescent light. About three days later observe and record the phenotype of the seeds, making a chi-square of results and recording it into correct tables.
