Morphology
zygosity = zygote (semi-transparent) = zygo + ity
Formed from the combining form 'zygo-' plus the noun-forming '-ity'; the components reflect pairing/joining but are technical combining forms not familiar to general learners.
Etymology
The word zygosity comes from the Greek root zygo- meaning 'yoke' or 'pair', like a wooden yoke that joins two animals. So zygosity is about whether two copies of a gene are the same or different.
