I mean there have been reports of Bigfoot for more than twenty years but that doesn't make him real. I am just kidding as that is definitely not a good comparison. My point is that it all anecdotal evidence describing a pretty complex genetic situation, so it doesn't seem pertinent to draw definite conclusions on. I definitely never said it was recessive. The spider blackhead project is an interesting idea academically, but from a breeding perspective it is a bit of a waste genetically. Seems like a lot of work to end up with normal looking animals, a few super black heads, and possibly a spider looking animal.
