Yogita Ingle 5 years, 1 month ago

A cross between two types of plants of same species considering only the transmission of one character is called monohybrid cross. For example, a cross between tall pea plants and dwarf pea plant that is considering only the height of the parents is a monohybrid cross. It will result in the formation of tall offsprings but they will be hybrid.

Representation of the monohybrid cross: character in focus is the height

Parents-     TT   X   tt

              (Tall)        (dwarf)

 

F1​-                     Tt

                  (Heterozygous tall)

On selfing:

                              Tt   X    Tt

F2​-                    TT   Tt    Tt     tt

Phenotypic ratio- 3 tall: 1 dwarf

Genotypic ratio- 1 homozygous tall: 2 heterozygous tall: 1 homozygous recessive
