Inbred for 2-3 generations at most to prove out your morph. Then outcrossed to very different animals. I have two bumblebees in my collection, they both carry spider and they both came from a founding animal but I would bet thousands that their COI is low as can be. There are thousands of spider morphs out there and to say that they are inbred is quite ridiculous. Same with retics, do you have any idea how many clark strain albino heterozygous and homozygous animals are out there? All came from one founder, all carry his genes, but virtually none of them carry a high percentage of the same genes now because they have been so heavily outcrossed to create new combinations.
