Solution

Crossing of homozygous tall TT with a homozygous dwarf (tt), is called Monohybrid cross. In this, all F1 progeny are heterozygous tall(Tt). In the F2 generation, 1 homozygous tall(TT), 2 heterozygous tall(Tt), homozygous dwarf(tt), genotypically. Phenotypically, 3 tall and 1 dwarf plants are present.
So, the correct option is D. 1(TT) : 2(Tt) : 1(tt)
