Answer and Explanation
Mendel selected a group of dwarf plants and sel pollinated them by dusting mature pollen grains onto them. He then collected the resulting seeds and planted them and noticed these seeds germinated and grew into dwarf plants only.
He also selected tall plants and self-pollinated them. the resulting seeds he observed that they grew into a micture of tall and dwarf plants. He took the seeds of tall plants only and repeated the experiments for many generations until he obtained only tall plants.
He then crossed cross-pollinated purebreeds tall garden pea with pure breed variety. He planted the seeds and observed the offsprings were all tall plants. He crossed two of these tall offsprinf from the F1 and planted the resulting seeds. the second filial generation consisted of a mixture of tall and dwarf plants.
He counted these plants and noted that the ratio of tall to dwarf was about 3:1. From this, he postulated that there are now laws governing inheritance.The law of independent assortment and law of segregation.
