The genotype is the part (DNA sequence) of the genetic makeup of a cell, and therefore of an organism or individual, which determines a specific characteristic (phenotype) of that cell/organism/individual.[1] Genotype is one of three factors that determine phenotype, the other two being inherited epigenetic factors, and non-inherited environmental factors.
