A biological term referring to the structural arrangement or organization of genes within a living organism's genetic material.
From Greek 'genos' (kind, race) + 'nema' (thread), combining the root for genetic material with the root for thread-like structures, reflecting how genes were historically understood as components of cellular threads.
This word sits at the intersection of old and new biology—it was coined when scientists could see thread-like chromosomes under microscopes but couldn't yet understand what genes actually were, so they created this term to describe the physical arrangement of hereditary factors.
