Morphology

dominance = dominant + dominate (semi-transparent) = domin + ance

The genetic sense names the property of an allele being 'dominant'; although directly related to 'dominant', it is a specialized technical usage that may not be obvious to all learners.

Etymology

Dominance comes from the old Latin word dominus, meaning 'master' or 'lord'. In genetics a 'dominant' gene acts like the 'master' and shows its trait while the other does not, so dominance means one gene controls what we see.
