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) |
