How do Mendel’s experiments show that traits may be dominant or recessive?

Explanation

The trait which appears in all the members of `F_(1)` generation and also in 75% numbers of `F_(2)` generaion obtained by self fertilization of `F_(1)` generation is dominant character. The trait which does not appear in F generation but after selfetilization of `F_(1)` generation, reppeears in 25% of `F_(2)` generation is known as recessive.
