WebVariations on Mendelian genetics Multiple alleles, incomplete dominance, and codominance In the real world, genes often come in many versions (alleles). Alleles aren't always fully dominant or recessive to one another, but may instead display codominance or incomplete dominance. Introduction Gregor Mendel knew how to keep things simple. WebYou can see from this discussion that the cell does not "know" that one gibberelline gene is dominant and the other is recessive. The cell is manufacturing enzymes from both copies of the gene.
