Codominance means that both of the parent's colors are combined with each other, usually having more dominant color. Incomplete dominance means that both the parent's colors are mixed with each other. For example, if the male dog is all black, and the female dog is all white, if it was codominance, the color would both be black and white, and whatever color is more dominant, that color would be more. If the dogs were incomplete dominance, then the colors would be mixed and get a different color.
