Morphology

dihybrid = hybrid (transparent) = di + hybrid

The prefix 'di-' meaning 'two' is transparently added to 'hybrid', indicating an organism hybridized for two traits.

Etymology

Dihybrid combines di- ('two') and hybrid ('a mix' or 'a cross'). So a dihybrid is a cross or offspring that involves 'two' different traits, which is why the word is used in genetics.
