being the biology idiot that I am, I can't seem to see the difference between these two terms? Both lead to heterozygotes which have a blend of their parents characteristics? Although I know blend isnt the right term since they 'seperate out when bred'..

PS, anyone else who is as fed up of Bio as I am...keep going! not long to go

With incomplete dominance, a cross between organisms with two different phenotypes produces offspring with a third phenotype that is a blending of the parental traits.
RED Flower x WHITE Flower ---> PINK Flower



With codominance, a cross between organisms with two different phenotypes produces offspring with a third phenotype in which both of the parental traits appear together.
red x white ---> red & white spotted

Both will look the same in a punnet square....but they appearence in phenotype will be different... really its the same concept..... which exam board are you doing...Im doing OCr and i no that incomplete dominance is taken as the same thing as codominance....
