In F1 generation;
There are 100% Tt Genotype and 100% Tall plant Phenotype
F2 Generation
F1 * F1

In F2 Generation;
Genotype
There are 25% TT (homozygous dominant, tall plants).
50% Tt (heterozygous tall plants), and
25% tt (homozygous recessive dwarf plants).
This is how dwarf characteristics reappear in the second generation.
The Phenotype of F2 generation is 3:1 (Tall : Dwarf)
