Etymologically, the entry records: 19th century: from German Chromosom, ultimately from Ancient Greek χρῶμα (khrôma, “colour”) + σῶμα (sôma, “body”) (because they are stained under the microscope). Equivalent to chromo- + -some. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is chromosome, spelled C-H-R-O-M-O-S-O-M-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
