Mendel prevented self-pollination by the pea plants by removing the pollen-bearing part of the plant.
Mendel conducted several plant breeding experiments to study how traits are inherited in living organisms using the pea plant.
In some of the experiments, he needed the plant not to self-fertilize. Thus, he decided to remove the polling-bearing part of such plants.
The pollen-bearing part of a plant is known as the anther. By doing so, the male gamete, which is the pollen, will not be available to fertilize the female gamete of the same plant.
