Morphology

deselection = deselect (semi-transparent) = de + select + ion

Morphologically it is built from 'deselect' + '-ion', but in evolutionary biology it denotes 'selection against' (a technical usage), so the meaning is domain-specific and not fully inferable by general learners.

Etymology

The word deselection comes from the prefix de- meaning 'remove' and selection meaning 'choosing', so in biology it means a gene or trait is 'chosen against' and becomes less common in a population.
