Phenotype: Meaning and Definition
A phenotype is the observable physical appearance, biochemical characteristics, and behavior of an organism, which result from the interaction of its genetic makeup (genotype) and environmental factors.
Key Characteristics of Phenotype:
-
It includes visible traits like height, eye color, and hair texture.
-
It also involves biochemical and physiological traits like blood type, metabolism, and disease resistance.
-
The same genotype can produce different phenotypes under different environmental conditions (e.g., identical twins may look slightly different due to lifestyle differences).
Examples of Phenotypes:
-
Physical Traits – Blue eyes, curly hair, tall height
-
Biochemical Traits – Blood type (A, B, AB, O), lactose intolerance
-
Behavioral Traits – Aggressiveness, intelligence (partly genetic, partly environmental)
-
Disease Susceptibility – Genetic disorders like sickle cell anemia
Phenotype vs. Genotype:
| Feature | Phenotype | Genotype |
|---|---|---|
| Definition | Observable characteristics of an organism | Genetic makeup (DNA sequence) |
| Influenced by | Genes + Environment | Inherited genes from parents |
| Example | Brown eyes, tall height | BB, Bb (for brown eye color) |

Phenotype – Meaning and Definition
Definition:
Phenotype refers to the observable physical characteristics or traits of an organism, which result from the interaction of its genetic makeup (genotype) and the environment.
Meaning in Simple Terms:
A phenotype is what you can see or measure in an organism — like its eye color, height, skin tone, or blood type.
It is the outward expression of the genes (genotype), often influenced by environment.
Genetics Example:
-
Genotype: BB or Bb (gene for brown eyes)
-
Phenotype: Brown eyes (the actual trait you see)
Even though two people may have different genotypes, if they both have at least one dominant gene (like B), their phenotype will look the same.
Key Features of Phenotype:
-
Influenced by genes (genotype) and environment
-
Includes physical traits (e.g., eye color, height) and biochemical traits (e.g., blood type, enzyme levels)
-
Can change due to environmental factors (e.g., skin tanning, weight)
Summary:
Phenotype = Physical expression of genetic information
It is what you see, not just what is coded in the genes.
Example Table:
| Trait | Genotype (Genes) | Phenotype (Trait) |
|---|---|---|
| Eye Color | BB or Bb | Brown Eyes |
| Blood Type | AA or AO | Blood Type A |
| Height | Multiple genes | Tall or Short (affected by nutrition too) |
