Genotype vs. Phenotype. Thegenotype of an organism is the genetic code in its cells. This genetic constitution of an individual influences – but is not solely responsible for – many of its traits. Thephenotype is the visible or expressed trait, such as hair color.

Genotype Phenotype
DEFINATION The genetic makeup of an individual. Refers to the information contained on two alleles in the cell. Detectable expression of the genotype. An expressed and observable trait. e.g. hair color.
Examples
DNA, susceptibility to diseases Hair color, eye color, weight, the ability to roll one's tongue
Depends upon
The hereditary information that was given to an individual by their parents. Genotype and the influence of the environment.
Inheritance
Partly inherited by offspring, as one of the two alleles is passed on during reproduction. Cannot be inherited.
Contains
All the hereditary information of an individual, even if those genes are not expressed. Expressed genes only.
Can be determined by
Genotyping – using a biological assay, such as PCR, to find out what genes are on an allele. (Inside the body) Observation of the individual. (Outside the body)
