ANY other morph can be combined with the diffused pattern gene that makes 'bloodreds'.
For homozygous genes, and so far as I'm aware with the current trade names:
Diffused alone = "Bloodred" or "Diffused" (though your result may not be dark red or particularly diffused)
Charcoal + Diffused = Pewter
Anery + Diffused = Granite
Amel + Diffused = Fire (This would include 'sunglow' or 'reverse okeetee' or 'candy cane' by the way)
Lavender + Diffused = Plasma (YARRRGH... "Amethyst". Come on! Say it!)
Caramel + Diffused = "Caramel Bloodred" (no trade name yet)
Ultra + Diffused = "Ultra Bloodred" (no trade name yet)
Hypo + Diffused = "Hypo Bloodred" (no trade name yet)
Lava + Diffused = "Lava Bloodred" (no trade name yet)
Striped + Diffused = "Striped Bloodred" (no trade name yet)
Motley + Diffused = "Motley Bloodred" (no trade name yet)
Anery + Amel + Diffused = Avalanche (Snow Blood)
Anery + Hypo + Diffused = "Ghost Bloodred" (no trade name yet - I like "Titanium", so I'll suggest it now *grin*)
Charcoal + Hypo + Diffused = "Phantom Bloodred" (no trade name yet)
Caramel + Hypo + Diffused = "Amber Bloodred" (no trade name yet)
Amel + Caramel + Diffused = Sulfur (Butter Blood)
And that's about me tapped out for what I can work out right now *grins*
I don't think I've ever seen an adult Striped Blood (or any homozygous stripe+diffuse regardless of other morphs) - seems a bit counterproductive to combine two pattern morphs, though I suppose it'd get you a more patternless snake than the standard blotched. Same goes for Motley.
