Domestic Swan X Graylag Goose.

I think that there is a domestic version of Swan Goose that retains the bill knob and the thin-and-long neck with smooth plumage (not ruffled) of Swan Goose but sports white plumage and orange bill. At least, it seems to me to go against logic to have an obvious and large bill knob on an entirely orange bill if it's a hybrid. My experience with hybrids among these beasts is that the black of the Swan Goose bill usually shows into the second generation post-hybridization. Don't quote me on it, but that's my interpretation. I have no actual knowledge of of the genetics of these white-plumaged, long-necked, thin-necked, smooth-necked, bill-knobbed domestic geese is, but I don't see anything in them that points to Graylag, except for the bill color.

So would you say it's a straight Domestic Swan Goose, no Graylag?
