Solution

The correct option is D 1 : 2 : 1 : : Tall homozygous : Tall Heterozygous : Dwarf
Monohybrid cross is generally the cross between a single pair of contrasting characters. Law of dominance states that in a pair of alleles one is a dominant character and other is a recessive character. Only the dominant character will show itself in the heterozygous trait. The recessive character can show itself when it is present in a homozygotic condition.
The genotypic ratio in monohybrid cross is the 1 : 2: 1

So, the correct option is '1 : 2 : 1 : : Tall homozygous : Tall Heterozygous : Dwarf'
