The term 'phene' was evidently coined as an obvious parallel construct to 'gene'. Phene is to Phenotype as Gene is to Genotype, and Similarly Phene is to Phenome as Gene is to Genome. More specifically, a Phene is an abstract concept describing a particular characteristic which can be possessed by an organism. Whereas Phenotype refers to a collection of Phenes possessed by a particular organism, and Phenome refers to the entire set of Phenes that exist within an organism or species.
