With the help of an example justify the following statement:
"A trait may be inherited, but may not be expressed."
Solution:  
Characters are inherited by parents. But not all the characters are expressed. Some characters are recessive and they are suppressed by dominant genes.
E.g., In one of the Mendel's experiments when pure tall pea plants are crossed with pure dwarf pea plants in F1 generation all tall pea plants are obtained. On selfing F1 generation pea plants both tall and dwarf pea plants were obtained in F2 generation.
