Morphology
nonhomologous = homologous (transparent) = non + homolog + ous
The negative prefix 'non-' is directly attached to the adjective 'homologous', yielding a straightforward negation 'not homologous'.
Etymology
Nonhomologous comes from the parts non- 'not' and homo- 'same', as in homogeneous, which helps you remember the 'same' idea. So, nonhomologous describes things that are 'not the same' in origin or structure, for example proteins or chromosomes that do not come from the same source.
