So from what I've gathered:
Incomplete dominant mutations have similar phenotypes in heterozygous and homozygous forms. When an organism with the mutation is crossed with another unrelated organism the resulting offspring will show similar characteristics of both. Does this make sense, I'm not sure how well I am explaining myself.
I, like Ryan, have been taught by the flower principle. The Red X White = Pink.
Since Hypos have a variety characteristics, and I don't know of any other mutations that could be classified as incomplete dominance (other than wild type) I will use this example. Crossing two hypos with different characteristics will create offspring with components of both. Such has been done by using striped, abberant, high-color, low-speckled, broad saddled, etc.
Now this can also be classified as selective breeding, which it may be better to do so. But so can the flower. By crossing the light color of the white flower and the pigment of the red flower the goal would be a light pigmented flower, pink. So the same can work with Hypo traits. And it has worked. In other mutations with variables everything seems to work at random, but in Hypos breeding certain traits results in certain results. Since these traits are not 100% connected with the Hypo mutation, but are by-products I think of them as the incomplete factors of the mutation.
I mentioned that wild-type boas could be labeled as incomplete dominant as well. We know that wild-type is dominant over recessive mutations, but that wild-type animals with different characteristics can be crossed for new results that are a combination factor.
I realize some of this may sound a little off, I'm not the best at explaining my thoughts. At any rate, what do you think? Right, wrong, good idea, why did I ever come up with it?
