| Points of Comparison | Genotype | Phenotype |
|---|
| Definition | A set of genes in DNA that are responsible for unique characteristics or traits are called genotype. | The physical characteristics or appearance of an organism is called phenotype |
| Observable | Genotypes are present within an organism’s chromosomes. | Phenotypes are observable characteristics and they can be seen on an individual’s body. |
| Inherited | Genotypes are partially inherited. | Phenotypes are non-inherited |
| Affected by | Genetic compositions can affect genotypes. | On the other hand, an organism’s genotype can affect phenotype. |
| Consists of | It consists of an organism’s hereditary characteristics. | It consists of different characteristics of an organism, for instance, an individual’s development, physiological and biological properties, and behavior, etc. |
| Determined by | The process of genotyping in various scientific methods like PCR determined genotypes. | By observing an individual, phenotypes can be easily determined |
| Relation | Same genotypes usually result in the same phenotypes. | But the same phenotype may not obtain from the same genotype. |
| Changes | It remains the same throughout the entire life of an individual. | It may change throughout an individual life. |
| Examples | Genotype examples seen in different organisms for instance are the homozygous allele for height, the heterozygous allele for height, and the homozygous allele for eye color. | Phenotype examples are seen in different organisms for instance are eye color, blood group, and hair color, etc. |
