➦This law gives the explanation for expression of only one of the parental trait in F1 hybrid.

➦This law states that out of a pair of contrasting characters only one is able to express itself phenotypically in F 1 hybrid called as dominant while the alternate form remains hidden and called recessive.

➦ In a cross between true breeding tall pea plant and a true breeding dwarf pea plant, all the plants of F1 generation were tall.

➦When the F 1 individuals were self-pollinated it was observed that the tall and dwarf plants in F 1 generation were in the ration 3: 1

➦ further, when dwarf plants were self-pollinated, the successive generation produced only dwarf plants showing their homozygous/true breeding nature.

➦On self-pollination of tall plants, some of them produced only tall plants in successive generations while others produced both tall and dwarf plants showing their Heterozygous nature.
