Both $(b)$ and $(c)$
Which one of the following cannot be explained on the basis of Mendel's law of Dominance ?
An allele is said to be dominant if
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
If a plant heterozygous for tallness is selfed, the $F_2$ generation has both tall and dwarf plants. This proves the principle of
Organism of pure line is that which produce individuals of
