Morphology
vitellogenin = vitellogen (opaque) = vitellogen + in
The immediate base is a technical combining form ('vitellogen') plus the protein suffix '-in', which is not a familiar productive morpheme to average B1 learners.
Etymology
The word vitellogenin comes from the parts vitell- meaning 'yolk' and -genin meaning 'to make', like in the English word 'generate'. So, vitellogenin is a protein made to form the egg 'yolk', which is why scientists measure it to check animal health and egg production.
