Sir Ronald Fisher analyzed this problem thoroughly back in the early days
of population genetics. You should read his discussion of the evolution
of dominance in "The Genetical Theory of Natural Selection" first
published in 1929 but pretty constantly in print for many years and
available in most libraries. Absent any molecular knowledge, Fisher
still perceived that dominance will evolve and that different
pleiotrophic aspects of the same genotype will evolve different
dominance. Experimental work has always supported Fisher's view.
