I'm fortunate enough that I do have 20 snakes to compare.

I have bred my bloodred female to a different male of a different morph every year since 2006 creating outcrossed bloodreds that are each in effect the first step of a two generation process of creating morphs such as sulphurs, avalanches, peppers, fires, etc.

It seems more like the bloodred genetics work through an incomplete dominancy in where some of the 'blood red' bleeds through onto the outcrossed hatchling. No matter what I breed my bloodred to I have ended up with high red normals with many showing some diffusion along their sides and a good number of them with a reduced belly pattern. The bellies will have pattern along the sides but it looks like someone took an eraser right down the middle of the belly leaving the middle strip of belly patternless.

This year I bred my bloodred to a butter motley and have the reddest outcrosses I have seen yet. The snake pictured is one of those babies and for the outcrossing I've done, this one has a rather extreme amount of red in it.

From what I have observed through my own breeding the bloodred genetics are not simple recessive....there is no het bloodred, only outcrosses, and they are not codominant either, but incomplete dominant with the some of the 'bloodred' bleeding out onto the first generation hatchlings.
