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)
