Detailed explanation-1: -Mendel cross-bred peas with 7 pairs of pure-bred traits. First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits.
Detailed explanation-2: -Mendel called the visible form the dominant trait and the hidden form the recessive trait. In the second generation, after plants were allowed to self-fertilize (pollinate themselves), the hidden form of the trait reappeared in a minority of the plants.
Detailed explanation-3: -To test this prediction, Mendel allowed the F1 generation plants to self-pollinate. He was surprised by the results. Some of the F2 generation plants had white flowers. He studied hundreds of F2 generation plants, and for every three purple-flowered plants, there was an average of one white-flowered plant.
Detailed explanation-4: -These plants were dubbed the P generation by him (for parent). He then bred two distinct true-breeding P plants to create a second generation of plants (F1). He then self-pollinated two F1 generation plants with the same features to create a third-generation (F2).
Detailed explanation-5: -Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice.
