If dwarf pea plant was treated with Gibberellic acid, it grew as tall as the pure tall pea plant. If this treated plant is crossed with a pure tall plant then the phenotypic ratio of is likely to be

Organisms phenotypically similar but genotypically different are said to be

If a plant heterozygous for tallness is selfed, the $F_2$ generation has both tall and dwarf plants. This proves the principle of
