Using the five plants that you grew, cross any plant with itself or with another plant. Mendel choose pea plants for his experiments because of nated purple- and white-flowered parent plants. Mendel took a purebred tall and a purebred short plant for his experiment. In the 1800s, Gregor Mendel figured out basic patterns of inheritance by breeding pea plants and observing whether the offspring looked like either parent plant. Figure 5. Mendel chose to experiment with peas because they possessed four important qualities: By experimenting with pea plant breeding, Gregor Mendel developed three principles of inheritance that described the transmission of genetic traits before anyone knew exactly what genes were Mendel’s experiments extended beyond the F 2 generation to the F 3 generation, F 4 generation, and so on, but it was the ratio of characteristics in the P, F 1, and F 2 generations that were the most intriguing and became the basis of Mendel’s postulates. Whether the plan upon which the separate experiments were conducted and carried out was the best suited to attain the desired end is left to the friendly decision of the reader. Mendel came from a family of farmers, and he knew a thing or two about plants. The F1 plants were allowed to self-fertilize, and the F2 generation included both purple and white flowered plants. Seven traits were used by Mendel, including smooth or wrinkled ripe seeds, yellow or green seed albumen, purple or white flower, tall or dwarf stem length, and others. His meticulous experiments, conducted in the mid-19th century, laid the groundwork for our modern understanding of heredity. Mendel’s experiments extended beyond the F 2 generation to the F 3 generation, F 4 generation, and so on, but it was the ratio of characteristics in the P, F 1, and F 2 generations that were the most intriguing and became the basis of Mendel’s postulates.
