Morphology

unit + character

The compound is transparently composed: 'unit' (one discrete thing) modifies 'character' (a trait or attribute), so a B1 learner who knows both words can infer it refers to a single, discrete trait. Although the term is technical (genetics) and the precise all-or-none inheritance detail may require domain knowledge, the basic meaning is directly derivable from the constituents and follows a common modifier+noun pattern.

Etymology

Unit character comes from early genetics and gives a simple picture: a single unit determines a visible character, or 'trait'. If that unit is 'present' the character shows and if it is 'absent' it does not, so the term describes a trait controlled by 'one gene' in an 'all-or-none' way.
