Statement - I : In his monohybrid cross with tall and dwarf pea plants, Mendel concluded that all tall plants in the generation are not similar genotypically                                           

Statement - II : When Mendel self pollinated F2 plants some of the tall plants produced only the tall plants and other tall plants produced both tall and dwarf plants.

If F₁self pollinated in the F₂ generation homozygous tall (TT) and heterozygous tall

(Tt) and also homozygous short (tt) plants are formed So, two different genotypic tall plants are

formed i,e TT and Tt. When mendel self pollinated F₂ plants some of the tall plants produced only tall plants and other tall plants produced both tall and dwarf plants.

TT        Tt        tt   ------------ F₂ generation

TT x TT           Tt  x Tt                 tt x tt ----------- F₂ self cross

TT            TT               Tt                                    tt               tt -----------    F₃ generation
