Phenotypic trait
A phenotypic trait, or simply trait, is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two. For example, eye color is a character of an organism, while blue, brown and hazel are traits.

Phenotypic trait is the element the descriptions of individuals and groups of living creatures. Individualized biological variability (biodiversity) of each species and populations of living beings, includes all the components of individual features or individuality and group identity in morphological and anatomical, biochemical and ethological, and every other way, from the level of molecules to living communities and a higher degrees of ecological integration.
Individuals and groups differ among themselves biologically, in practically endless succession of more or less visible elements of their descriptions, which are named as trait, feature, mark, nature, characteristics, character and others.
