California game and fish has very strict rules about what types of fish are legal. Fear of ecological damage I think.
And about the recessive gene issue, when the fish is altered, both sets of genes in both parents can be spliced, passing that gene 100% of the time and expressed 100% of the time, because it's the only "type" of that gene available.
