Morphology

monozygotic + twin

The noun phrase is fully compositional: 'monozygotic' specifies origin from a single fertilized egg and 'twin' denotes one of a pair, so together they mean a twin from the same zygote sharing identical genetics. This is a scientific compounding pattern found across languages, so a B1 learner who knows both constituents would be able to derive the meaning.

Etymology

Monozygotic twin comes from the parts mono ('one') and zygotic ('a fertilized egg'). It paints the picture of one egg splitting into two babies who share the same genes, so they are genetically identical.
