Busts out a sheet of paper...

Yep, Somewhere between thinking of buying a snow corn and spewing out fractions, I messed up. Score 1: DrZot.

Ok, so in super-extended form (I didn't draw this thing for fun, ya know):

If you breed erythristic and melanistic snakes together, assuming niether or het for the other trait (het = heterozygous = has a dominant and recessive gene for a trait. A normal snake het for erythrism shows normal markings because of the dominant gene, but can contribute a recessive gene to offspring):

Generation 1:
16 normals double het for erythrism and melanism.

Breeding two of these together:
1 normal
2 normal het for erythrism
2 normal het for melanism
4 normal double het for both

1 erythristic
2 erythristic het for melanism

1 melanistic
2 melanistic het for erythrism

1 melanistic and erythristic (this is what you were looking for)

Kudos DrZot; I will now go put my head in a paper bag and shun myself.
