Ok so when considering selective breeding and how quality is affected lets just say you have a decent pastel and assuming you breed it to something that is a darker morph like say mahogany or ghi (I chose these because I think pastel GHIs and Mahoganies are just not very attractive) could a pastel be dirtied up by simply breeding it to something dark like that? I have heard a lot of different things suggesting that characteristics can be passed on without actually passing on the gene in particular. So in the case of breeding dark morphs to pastels could some of the dark characteristics be passed on to the babies even if the gene itself was not? I am not real good with genetics but I know what I like and thats what I plan to breed for. I try not to complicate things. I am not against breeding pastel to darker morphs I think it works in many cases but isnt that part of selective breeding? Deciding not to pair pastel with something because it could just muddy it up? I hope I am not confusing any body.
