With the help of an example justify the following statement: “A trait may be inherited, but may not be expressed”.
Answer:
Yes, it is possible that a trait is inherited but may not be expressed.
For example, when pure tall pea plants are crossed with pure dwarf pea plants, only tall pea plants are obtained in F! generation.
On selfing tall plants of F1; both tall and dwarf plants are obtained in F2 generation in the ratio 3:1. Reappearance of the dwarf character, a recessive trait in F2 generation shows that the dwarf trait was present in individuals of F1 but it did not express.
