Question

A trait may be inherited but may not be expressed . Justify the statement by giving example.

Answer 1

two examples
dwarf (recessive) , constricted leaf (recessive)

Answer 2

When a tall pea plant was crossed with a dwarf pea plant, the $F_{1} $ generation plants were all tall. When $F_{1} $ plants were selfed, the $F_{2} $ generation plants were not all tall; they were tall and dwarf plants.

This shows that the F_{1}  plants had inherited both the parental traits but did not express dwarfness/recessive in the presence of the trait for tallness/dominant.

hope this helped you
