From the Greek 'pheno', meaning 'display'. The usage of the word phenotype is a very broad conceptual term, referring to observed traits and characteristics of organisms based on physical characteristics including biological processes, biophysics, structure(s) and behaviors. The word is more efficient grammatically, creating a term covering the descriptors than as categorization in practical forms, describing these very variable subjects. Phenotypes refer to an array of heterogeneous forms of data, across a wide spectrum of materials, rather than a specific class of information.
