So has anyone heard/seen variations in the quality with some mojave pastels not showing the obvious combo but later proving through breeding?

I got a response from someone on kingsnake who had excellent odds producing obvious combos in a small clutch but I remember when the Snake Keeper was trying to produce the first one they apparently missed the first several clutches. Got me wondering if sometimes for some unknown reason one of these mutations can hide the other making the genetic combo pass as either a pastel or a mojave.
