Morphology

dominant = dominate (transparent) = domin + ant

The adjective 'dominant' is clearly derived from the verb 'dominate' using the suffix '-ant', indicating a characteristic of having control.

Etymology

Dominant comes from the Latin dominus, which means 'lord' or 'master'. So in genetics a dominant gene is like a 'ruler' that shows its trait even when the other copy is different.
