Difference Between Genotype and Phenotype

Th terms Genotype and phenotype sound similar but they actually mean different. The genotype is a set of genes in DNA responsible for unique trait or characteristic while the phenotype is the physical appearance or characteristics.

Genotype and Phenotype

Genotype and Phenotype


Human genetic coding could be found by their genotype. It determines which traits or characteristic to show. Organisms with the same genotype do not necessarily look similar. The behavior and appearance change periodically. Meanwhile, organisms that look same do not have the same genotype. The identification of genotype could be only done by the process of biological test and could not be identified through observations.


Like discussed earlier, both the genotype and phenotype sounds similar but has differences. The phenotype is determined by an individual’s genotype and expressed genes or by visible trait, for instance, hair color or type, eye color body shape, and height. It depends on the genotype but also influenced by the factors in the environment.

Difference Between Genotype and Phenotype
Genotype Phenotype
DNA, Influenced to diseases are few examples Eye color, hair color, body shape, weight are few examples
The genetic makeup of an individual. Visible expression of genotype
Partly inherited Could not be inherited
Determined by biological tests Could be observed of the individual.
