Punnett Square for Mendelian monohybrid cross between pure line tall and the dwarf planet will appear as follows:
Parent Generation
TT x tt
↓
F1 Generation Tt
↓
Tt x Tt
(Selfing)
F2 Generation
| T | t | |
| T | TT | Tt |
| t | Tt | tt |
The result of F2 generation phenotypic ratio of a monohybrid cross is 3: 1.
