Question

4. How do Mendel's experiments show that traits may be dominant or recessive​

Answer 1

$\textbf{Answer:-}$

• When Mendel crossed pure tall (TT) pea plants with a pure dwarf (tt) pea plants, in the F1 generation he found that all pea plants were tall (Tt).

• There were no dwarf plants produced in an F1 generation. When he self-pollinated these F1 plants, in the F2 generation he obtained tall and dwarf plants in the ratio 3:1.

• Thus as three-fourths of the plant in an F2 generation are tall and one-fourth is dwarf so tall is a dominant trait whereas dwarf is a recessive trai which expressed itself only in homozygous condition).

• So he concluded that for a particular trait [here in this example height of the plant] it may be dominant or recessive.
