$A$ trait may be inherited, but may not be expressed. Justify this statement with the help of a suitable example.

(N/A) When a tall pea plant was crossed with a dwarf pea plant, all plants in the $F_{1}$ generation were tall.
When these $F_{1}$ plants were self-pollinated, the $F_{2}$ generation consisted of both tall and dwarf plants.
This observation confirms that the $F_{1}$ plants inherited the genetic information for both parental traits (tallness and dwarfness).
However, the trait for dwarfness remained unexpressed in the $F_{1}$ generation because it is a recessive trait, which is masked by the dominant trait for tallness.
