What is phenotype?

Phenotype refers to the observable physical, physiological, and behavioral characteristics of an organism.

It is the expression of the genotype in combination with environmental influences. In simple terms, phenotype is what we can see or measure, such as height, eye color, skin color, or blood type.

While genotype provides the genetic blueprint, phenotype is the actual outcome of how those genes are expressed in a specific environment.

For example, two individuals may have similar genes for height, but differences in nutrition can lead to variations in their actual height.

Phenotype helps in understanding how genetic traits are expressed in real-life conditions.
