Morphology

repressive = repress (semi-transparent) = re + press + ive

Formally derived from 'repress' + '-ive', but the applied meaning in genetics (suppression of gene expression) is domain-specific and may not be inferable to non-specialists.

Etymology

Repressive comes from the Latin reprimere, made of re- 'back' and press, like the English word press, meaning 'to press back'. So in biology a repressive state 'presses down' on a gene, making the gene less active or turning it off.
