Question

how do Mendel's experiment show that traits may be dominant or rececive

Answer 1

Mendel demonstrated that traitscan be either dominant or recessivethrough his monohybrid cross. He crossed true-breeding tall (TT) and dwarf (tt) pea plants. ... They appeared tall only because the tall trait wasdominant over the dwarf trait. Thisshows that traits may be dominant or recessive.
