Personally, I believe that bloodred is recessive, but I think that it is the combination of multiple simple recessive genes.
My own limited experience has already disproven that. I bred a blood to an amel and got a multitude of hatchlings expressing partial effects, such as the white stripe down the center of the belly. If bloodred components were all recessive, none of this would show up, it would be either On or Off.
I believe I heard Rich say before that he had gotten predictable results from breeding bloods. I'd have to hear from him to be sure what his exact position is.
Best I can tell one trait does act like a simple trait, which is the patternless belly. This is also the common "qualifier" for bloodreds. So from at least one perspective, IMO it is valid to say that "bloodred" is a simple (although I won't say recessive) trait.
I think the thing people don't take into account is that the "pure" look of the original bloodreds (the thin borders, lack of contrast, total lack of belly checkering and even peppering) was likely influenced by the ancestry of the originals. Other influences (such as Okeetee heritage or other complex pattern and coloration variations) can offset the "pure" look that people generally associate with the ideal bloodreds. IMO this is why it is difficult to use "outcrossed" bloods to recover a "pure" specimen.
For example, if the originals came from stock that already had very weak belly patterning, it could easily be assumed that the "trait" controlling plainbelly was a simple on/off thing. But cross in other influences, such as one with super-bold belly checkering, and that heritage asserts its influence and creates lots of peppering on the belly. Then it could be assumed that the pure white belly was due to multiple genes, and some of them were being lost with each outcrossing.
However, if it really is the case that the checkering is removed in a predictable ratio approximating 1:4 when breeding "het to het" then--whether or not the black speckling is present or how much of it there is--I think it is a reasonable logical conclusion (for the time being) to say that the "plainbelly" trait is a simple trait. I'd be curious to see if the "pure" plain belly look could be recovered again by breeding these speckle-bellied outcrosses to something with a more weakly-patterned belly...
candy canes only come from the HYPO and Milksnake phase corns!
Candycanes are not hypo milksnake phase, they are exceptional examples of amelanistic Miami-like corns. But don't mistake this to mean that any amelanistic miami is a candy cane. It takes a lot of selective breeding to achieve that goal.
So, whenever I hear someone lamenting about the 1/64 odds of getting a triple homozygous hatchling from triple hets, I always tell myself that there is also only a 1/64 chance of getting a simple normal too.
Heh heh, I won't be lamenting about that one. I have a pair of snows from a bloodred mother.

I'm not interested in producing 63 "boring" corns just to find out what one snow-blood looks like.
