Why would that make any difference...and I'm truly curious to your thoughts, not being combative. Spiders still wobble when combined with other mutations. The thought process behind mutations essentially being "fixed" by entirely separate mutations is baffling to me...but then again, I don't claim to be well versed in genetic mutations or how they work.
You are correct...you can not fix a morph just because you mix that morph...I am sure someone will correct me if I am wrong...
For example...Spider and Sable proven to be fatal...if you were to combine an extreme morph....lets say a Spider Pin Lesser Ghost Pastel to a Sable Mojave Yellow Belly Orange Dream and in that clutch any baby that had the Spider Sable gene in the same baby it would not make it....when those two morphs cross the same path results will be the same no matter how many other morphs are present.
So you can't solve the problem of Desert females throwing infertile eggs just because its crossed into other genes....that gene still plays a roll....
Anyone can correct me if I am wrong...I know I have been wrong before....
