Possible`s father was an adult import. At the time Poss was hatched I don`t think there were any breeding size captive bred Pastels.
I know the only way to "prove" Poss is to breed him and see what he sires. For now I refer to him as a very pretty Pastel sibling. 
What would be different on his tummy? It is very yellow and that extends up his sides a bit. I need to get some pictures of that. The picture I posted is a scanned photo and not digital.
"Was Possible's father an imported pastel or one of the early captive bred ones? Maybe the grandmother was a nicer looking normal. Who knows, maybe some of these high yellow “normal” things could be recessive (or of course polygenetic).
I guess it just comes down to if you can always identify a pastel. Maybe the bellies could help.
Since pastel is a single gene they either have it or they don't. If the pastel siblings that didn't get the pastel gene are often above average looking it has to be due to something other than the pastel gene (which they didn't get). I'm just speculating that there has been some selection pressure to get some nice bright "normal" genes into the pastel lines. Even for the first breedings they may have been looking for compatible females thinking it might be recessive and picked some very pastel like normals."
