What is variation?

Variation refers to the differences in characteristics or traits among individuals of the same species.

These differences can be observed in physical features such as height, color, shape, and also in behavioral and physiological traits. Variation occurs due to genetic factors, environmental influences, or a combination of both.

Genetic variation arises from differences in genes inherited from parents, while environmental variation is influenced by factors such as diet, climate, and lifestyle.

Variation is important for the survival of a species, as it allows organisms to adapt to changing environmental conditions and contributes to the process of evolution.
