D)the interaction of two genes with complete dominance,resulting in four different phenotypes.
E)None of these

Question

Quizplus · Accepted Answer

The comb shape in chickens is indeed controlled by the interaction of two genes, each exhibiting complete dominance, and this genetic interaction results in four distinct phenotypes. This is a classic example of how genes can interact in a non-additive manner to produce various phenotypes.
