Mendel conducted breeding experiments on Pea plants.
(i) He selected pure bred tall and dwarf plants.
(ii) He cross-pollinated these plants.
(iii) In the F1 generation, he obtained only tall plants. Tallness is the dominant trait.
(iv) Then he produced F2 generation by selfing of hybrids/ F1.
(v) He found that 3/4th of the plants were tall and 1/4th were dwarf.
(vi) The trait which remains hidden in F1 generation plants is the recessive traits.
