phenotype
FEE-noh-type
/ˈfiːnətaɪp/
The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
What you see (physical traits, biochemical properties, behaviors, etc.), which is a product of both genetic makeup and environmental influences.
The story behind the word. Coined in 1909 by Wilhelm Johannsen (who also coined 'gene' and 'genotype'), 'phenotype' combines the Greek phainein ('to show' or 'to appear') with typos ('type' or 'impression'). It literally means 'the type that shows,' referring to the observable characteristics of an organism that are apparent to an observer.
Word relationships
- observable traits: More descriptive and less technical.
- expressed characteristics: Emphasizes the manifestation of genetic potential.
- genotype: The genetic makeup, not the observable traits.
Commonly confused with
- genotype: The 'phenotype' is the observable expression of traits, while the 'genotype' is the underlying genetic code that contributes to those traits.
Collocations
- observable phenotype
- disease phenotype
- complex phenotype
Example sentences
- "Even identical twins, with the same genotype, can have slightly different phenotypes due to varying environmental experiences." Explaining observable traits.
- "The plant's vibrant flower color is a striking phenotype, influenced by both its genes and the soil's nutrient content." Referring to a specific characteristic.
Memory hook
'Phenotype' is the 'PHysical' appearance, what you can 'PHoto.' Physical appearance.
When not to use
Don't confuse 'phenotype' with 'genotype' (the underlying genetic makeup). The phenotype is the expression of the genotype.
Fun facts
- Your blood type is an example of a phenotype.
- The phenotype of a chameleon changes dramatically with its environment, despite its underlying genotype remaining constant.
