Morphology

reversion = revert (transparent) = revert + ion

The sense in biology/genetics describes a 'return' to an earlier trait and is directly derived from 'revert' + '-ion'.

Etymology

Reversion comes from re- 'back' and vert 'turn', the same idea you see in reverse, meaning a 'turning back'. That's why in biology a reversion is the return or reappearance of an earlier trait.
