In one of his experiments with pea plants Mendel observed that when a pure tall pea plant is crossed with a pure dwarf pea plant, in the first generation, F_(1) only tall plants appeared. (i) What happens to the traits of the dwarf plants in this case? (ii) When the F_(1) generation plants were self-fertilised, he observed that in the plants of second generation, F_(2) both tall plants and dwarf plants were present. Why it happened? Explain briefly.
