This morph is not like a super Pastel or bumble bee or pinstripe spider or pastel pied or even lavendar albino pied where it takes two morphes to create them. They find these mutations in the wild and then through selective breeding and inbreeding and working with hets and poss hets they prove the line some ressicive genes take years. Dom and codom genes can be proved in one generation.
Hope this helped clear up the mess.
