Question

explain the statement with the following example A trade may be inherited but may not be expressed

Answer 1

A trait may be inherited but may not be expressed .

Example :-

                  When Mendel crossed the tall tea plants of F1 generation ,he found that tall and dwarf plants were obtained in F2 generation.He noted that the dwarf trait  of the parent pea plant that disappeared in the F1 generation progeny re-appeared in F2 generation.Mendel concluded that the dwarfness trait of the parent pea plant were not lost.They were suppressed in the F1 generation to re-appear in F2 generation.In this way, Mendel called expressed traits of tallness as dominant or suppressed traits of dwarfness as recessive.
