Morphology

crossover = cross (semi-transparent) = over + cross

The biological meaning derives from the literal 'crossing over' action, but it denotes a specific technical process that is not fully predictable from the components alone. [Postprocessing: moved 'over' from base_words to prefix]

Etymology

Crossover comes from the parts cross ('to go from one side to another') and over ('across'). In genetics a crossover is when two chromosomes 'cross over' and swap pieces during the formation of egg or sperm, which is why it creates new mixes of traits.
