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

Add three seeds to the potting mix and cover seeds with little remaining potting mix. After the addition of the potting mix, use a dropper filled with water and water each cell until water drips from the wick. Then place the quads on a watering tray under the fluorescent light bank. Each cell should have an equal distance from the light bank. Quads should be three inches below the fluorescent light; the light should also be left on all day. Make sure all wicks are in contact with the mat that sits on the watering tray. Also watch out for the watering system regularly throughout the experiment. After four to five days record plants in the quads, giving their phenotypes in a table for each cell removed all but the strongest plant. At about day 14, two or three flowers open on most plants in which one begins pollinating as followed. Simply use a small fine tipped paintbrush and cross-pollinate all four plants with each other. Repeat the same step, in four days going. After the third pollination carefully remove all unopened buds by pinching them. Take away all new buds for the next two weeks or as necessary. Seeds are now ready to harvest after about 21 days after pollination. Carry the quads with plants away from the watering try while letting them dry for five days. Remove dried seedpods from the quads and roll them between your fingers to free the seeds from the pod. Count and store seeds in an envelope, labeled with your name and…
