I could try to find some of it for you, I started looking into this specific morph months ago so it’s just various sites, research over time, articles and breeders/people who have claimed to worked with the breed for a while. This site has some helpful information as well as google and following breeders of the morph your interested in, some of them share their knowledge through their blogs or websites.
The hardest issue I’m having is finding something up to date. The most “up to date” I could find is from 2017/18. It’s similar to the trans line, as a new morph it was only breed het to het, now it is safe to breed visual to het as the gene is strengthened but it is still not safe to breed two visual trans. So this has been hard as improper breeding can cause a lot of issues from health issues in your clutches to the gene getting weakened. It happened with another morph/ gene (I want to say trans but can’t say 100% it’s 1am lol) they had to rebuild it after years of building it becuse people were not breeding properly as they wanted quick results and profit.
So, really how new is the zero and witblit genes? Articles from 2017 state it’s still relatively new. It is highly important anyone wishing to breed follow proper breeding and ethics. Research is key, if you’re not sure don’t do it until you are sure. Most breeders are looking to sell, some buyers are wishing to breed. If a breeder sells weak genetics, or breeds morphs inappropriately and sells those babies and someone else breeds those, we are now spreading the bad genetics back into the bloodline (even if the babies from the one clutch are healthy there are still risk and does not prove this to be safe breeding).
I am not sure how or when it was deemed safe to breed visual trans to het after years of het to het only. But the best practice I follow is protecting the animals and genetics. So I won’t do anything without being 1000% sure it is safe, ethical and in best practices. Especially if I find conflicting information regarding the subject.
Sorry I couldn’t help more as I’m still looking for more information on this myself.
