Okay, wellll, I had been debating what if anything to post on this as I am not really sure what is appropriate and not appropriate for me to say. I quite recently had a conversation about this topic with someone who is very "in the know," but while it wasn't explicitly stated to me that the information I was given is proprietary and not to be shared, I still wasn't sure that I felt comfortable posting it on a public forum after a private conversation.

I do feel compelled to speak up, though, and say that I highly, highly doubt that culling or even any real "conspiracy" is the answer, and I cannot imagine any breeders doing this. Hoarding males, maybe. Culling males, no, I don't think so. I can't speak for everyone but I just find that difficult to imagine.

... I can say with relative certainty, based on what I know, that because of however the heck this gene is inherited (and no, I don't know that part -- and to my knowledge NOBODY really does), there are currently a LOT more females than males out there, so I reckon anybody who produces a male keeps him. So, I imagine that would be more likely to explain the lack of available males than a deliberate attempt to keep their numbers artificially low.

I will also say that to my knowledge, everything that OWAL posted -- the fact that CG females produce 50/50 male and female CGs, like a regular dominant, and the fact that male CGs from those female CG dams produce almost exclusively CG female and non-CG male offspring is correct from what I know.

... There is also a third part to the story, however, that as far as I can tell from skimming the Internet hasn't yet been revealed, and that seems to be the "key" to consistently making a bunch of male CGs. ... If you're lucky enough to stumble upon it. ... I don't know if that's all that appropriate to share at this time or not so for now I'll just leave it at that. (Sorry, I'm not trying to play the "neener neener I know more" game -- just don't want to blab someone else's information.) I really don't think there's any conspiracy though.

(PS. I will also say that it doesn't seem to be sex-linked recessive -- that was one of my first thoughts, too )
