Actually, I already know I'm a mutant, but I may be a mutant twice over.
My blog readers are the coolest people ever. Neek (who appears to be, sadly, blogless) dropped me a note about the concept of 'tetrachromacy', or having super-duper color vision due to a genetic mutation that leads to four (instead of three) types of cones in the retina. I've spent the morning reading up on it, going "hey, I do that" when they describe the behavior of tetrachromats. Mostly it involves things like color memory, seeing variations in color no one else does, and stuff like that. (One description involves an interior decorator who can see differences in paint chips that none of her clients do.)
Wikipedia has a decent basic article on it, here.
There is a better, yet basic, article here, that describes things better in terms of the human implications. It also has a link to the Ishihara color blindness tests, which can be fun to play with.
There is also an article, here, that goes into gory details on the genetics involved (WARNING: it is a PDF file). I tracked on about 75% of the details; I'm not a geneticist, and what little formal study I have in genetics involved plants (didja know ferns can have up to four hundred-odd chromasomes?) and not humans, which is more confusing than you'd first think.
Anyway, the basic gist is, women (only women, it's a double X chromasome deal, related to why men are color blind, basically the gene that controls that stuff is very prone to mutation and variation) can have FOUR types of color receptors in the retina, instead of the usual three. It's estimated that with three color receptors an average person can see about a million colors; with a fourth cone type, that number of visible colors would go up to a hundred million. At least theoretically. Seems that the color sensitivity of the cones is variable, though, even among 'normal' folks, so you get more a graduation of color sensitivity among people. So it's likely that even with the fourth cone, there would be a variation among individuals, as to how sensitive to color they are.
What's REALLY interesting to me is, the great debate these days in the medical community isn't about whether or not the fourth cone mutation happens; it's whether or not the human brain can adapt to it enough to make use of it. Considering I've seen case studies of a kid who had AN ENTIRE HALF OF HER BRAIN REMOVED (because of really bad Epilepsy) and WALKED OUT OF THE HOSPITAL a couple weeks after the surgery, I've got faith the human brain can adapt enough to make use of an extra cone in the retina. Particularly if it's an otherwise functional brain, which is usually the case these days.
I'm going to try to contact a couple of these guys who are doing studies, and see if there's some kind of color test I can take, to verify it. (There's also a genetic test, which I'm game for, but I imagine having me look at some color cards would be a lot cheaper.) I'm quite curious, now.
...I've been reading the behavior of known tetrachromats to the Husbeast, and he's laughing and saying "Oh yeah, that's you."
Oh, my other mutation? I was born without wisdom teeth. Don't have any, never did. I in no way think the genetic code dictating how my teeth come in is related to the genetic code that dictates how I see color is related. But it establishes my genetic weirdness, for sure.
