wyoming white lineage

It's well documented that to obtain the platinum percula you need two individuals from the picasso strain
Is the same trend true for the wyoming white ?

I don't know the whole answer but I know that you can get a wyoming white by breeding two "fancy whites" (pretty much an ocellaris version of a Picasso). If you look at Sustainable Aquatics website they state that a Fancy White (also called gladiator or divinci) is the result of breeding an ocellaris and a wyoming. It would be cool to have a centralized place to find the lineage of common varieties of clowns.

^ What Mike said
 
All the data and observations of myriad breeders suggests that the "Gladiator" gene (aka. the Wyoming White gene), the Gladiator being the originally wavy barred ocellaris from C-Quest, is akin to the picasso gene.  In both cases, partial dominance, which means +/+ = wild, gene/+ = Picasso / Gladiator aka. Davinci aka. Fancy White? etc..., and gene/gene = Platinum Perc, Wyoming White Ocellaris.

Mike talks about having a centralized place to find lineage...lineage is more about individual fish...what we really need is for standards to be accepted for the various genetic mutations that are known, and for standard shorthands to be adopted.  The MBI is the current organization in a position to take on such a task, but that's asking a lot of a group of volunteers already spread thin.  Hybrids are a whole secondary issue too...
 
Go see http://www.theangelfishsociety.com which will teach you both about the genetic fundamentals but also show you an organization which has adopted a set of standards and published them, ultimately being the leaders in how angelfish breeders now talk about their fish and genetics.
