self-derived threefold (chromosome sets)
Etymology
'autotriploid' originates from Greek 'autos' meaning 'self' combined with New Latin 'triploidēs' meaning 'three‑fold' (from 'tri-' = three + 'ploid' = fold/number of chromosome sets).
'autotriploid' was formed in scientific Neo‑Latin by compounding 'auto-' with 'triploid' (itself from 'tri-' + '-ploid'), and entered modern biological English usage in the 20th century to describe autopolyploid organisms with three chromosome sets.
Initially coined to denote a triploid condition derived from the same species, the term has retained this specific genetic meaning in modern usage.
