Incomplete dominance is not what you were implying, it is actually the partial presence of two traits which are equal in dominance. Codominant genes show both traits in full effect. An example I was given was horse hair: brown and black are both dominant to other colors, and if they are codom then you have both black and brown hairs on the horse. Incomplete dominance would show a mixtue, so a hair color in between the two.



Incomplete dominance is actually what many dominant snake genes are, like hypo boas. If it was a true codom, you would see black scales and hypo scales on heterozygous snakes. Since hypos are reduced black all over (but to a lesser extent than supers) it is an example of incomplete dominance.



Just clearing that one up for you a little.

It's just like the story of the grasshopper and the octopus. All year long the grasshopper stored up acorns for winter, while the octopus mooched off his girlfriend and watched tv. And then the winter came, and the grasshopper died, and the octopus stole all his acorns, and he got a race car. Is any of this sinking in?
