Introduction:
A genotype is the representation of the genetic complement of an organism, with respect to one or more characters. A phenotype is the observable morphological characters of an individual, which is the expressible form of genotype. Tallness/dwarfness, the red/pink/white colors of a flower are all its phenotypic traits, whereas TT/Tt, RR/Rr/rr are their genotypes, respectively.
