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, Fj only tall plants appear.
- What happens to the traits of the dwarf plants in this case?
- When the F, generation plants were self-fertilised, he observed that in the plants of second generation, F2 both tall plants and dwarf plants were present. Why it happened? Explain briefly.
- The dwarf traits of the plants is not expressed in the presence of the dominant tall trait.
- In the F2 generation, both the tall and dwarf traits are present in the ratio of 3 : 1. This showed that the traits for tallness and dwarfness are present in the I:generation, but the dwarfness, being the recessive trait does not express itself in the presence of tallness, the dominant trait.
