what is genotype and phenotype
please tell me very clearly about it.
Genotype: The genetic constitution of an organism is called genotype. It is the description of genes present in an organism. Genotype is always denoted by a pair of letters such as TT, Tt ot tt. Thus, the genotype of a tall plant could be TT ot Tt, while that of a dwarf plant is tt.
Phenotype: Phenotype refers to the observable characteristic or the expressed shown character of an organism. For example, being ‘tall’ or ‘dwarf’ are the phenotypes of a plant because these traits are visible to us. The phenotype of an organism is determined by its genotype. For example, genotype TT or Tt results in a tall phenotype and genotype tt results in a dwarf phenotype.
