Morphology

univalent = valence (opaque) = uni + valent

The cytogenetic sense ('an unpaired chromosome') is a specialized technical usage not directly predictable by a B1 learner from 'uni-' + 'valence'.

Etymology

Univalent comes from uni- 'one' and valent 'power', so it gives the picture of a single thing standing alone. That's why a univalent chromosome is one that stands alone and does not pair with its match during meiosis.
