WebGenetic sources of variation can themselves be divided into several subcategories, … 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.
