genotype and phenotype
Phenotype is the visible or morphological expression of the individual. It is the "outward, physical manifestation" of the organism or anything that is part of the observable structure, function or behavior of a living organism. Example - height, color, shape of nose etc.
Genotype is the genetic constitution of a particular individual (i.e. the particular set of genes it possesses.) Example - Tallness is represented by 2 genotypes - TT (pure tall) and Tt(hybrid tall)
