Morphology

polymorphism = polymorphic (semi-transparent) = poly + morph + ism

The noun is formed regularly from the adjective 'polymorphic' with -ism to express a state or property.

Etymology

Polymorphism comes from the parts poly- 'many', as in polygon, and -morph 'shape', as in metamorphosis. So in biology, polymorphism means a population has 'many forms' or types because of changes in its genes, which explains things like different butterfly wing patterns or why some individuals resist a disease.
