In Mendel’s experiment, when pure tall pea plants were crossed with pure dwarf pea plants, only tall pea plants were obtained in F1 generation.
On selfing the pea plants of F1 generation both tall and dwarf pea plants were obtained in F2 generation.
Reappearance of the dwarf pea plants in F2 generation proves that the dwarf trait was inherited but not expressed in F1 generation.
