Genotype shows the genetic constitution of an organism. In simple words, genotype is the description of genes present in an organism. Genotype is always A pair of letters such as TT, Tt or tt (where t and T are the different forms of the same gene). Thus, the genotype of a tall plant could be TT or Tt whereas that of dwarf plant is tt.
The characteristic (or trait ) which is visible in an organism is called it's phenotype. For example, being tall or dwraf (short) are phenotypes of a plant because these traits can be seen by us . The phenotype of an organism is actually it's physical characteristic which is determined by its genotype.

Monohybrid cross :)
Genotypic ratio is 1:2:1(TT,Tt,tt)
Phenotypic ratio is 3:1(tall:short)
Dihybrid cross :)
Genotypic ratio is 1:2:2:1:4:2:1:2:1
Phenotypic ratio is 9:3:3:1

Phenotypic ratio is 9:3:3:1
