The term 'gene' is derived from the Greek word 'genos' and the Latin word 'genus,' both meaning 'birth,' 'race,' 'kind,' or 'type.' Wilhelm Johannsen, a Danish botanist, first used the term 'gene' in 1909. He coined it to describe the units of heredity that Mendel had previously identified in his work on pea plants. Genes are thus called because they are the fundamental units that give rise to the inherited characteristics passed from parents to offspring, acting as the blueprints for individual traits and species.
