Okay, here's the deal. We are talking about genetics, which
can get complicated. I'll try to keep it simple. All the
morphs will 'work' together. They just might not produce what
you expect.
Albinos, pieds, axanthics, xanthics, ghost, stripe, and
several more recessive genes will all work together. The
problem is that they take a long time (which is why they
are very expensive). A recessive trait is a recessive trait.
For example, if you breed any 2 different recessive morphs
together, you will produce normal looking babies that are
100% het for BOTH genes (assuming both animals were displaying
the morphs to begin with). Breed a male and female that are
100% het for both genes, and you have a 1 in 16 chance of
getting an animal that displays both morphs. The snow ball
is the best example of this.
Rest assured, right now there are people working on albino pieds
and axanthic pieds and ghost pieds and albino stripes, and the
list goes on and on...
Note: Don't be confused by a different scenario of genes
appearing to 'not work together'. For example, axanthics.
There are a few different lines of axanthics (VPI, Jolliff,
SnakeKeeper) and they are not compatible. What that means is
that if you have a Jolliff axanthic male and breed it to a
VPI axanthic female, all your babies will be NORMAL looking.
Does that mean the genes 'aren't working'. The answer is no.
The genes ARE working, but just not the way you may have
expected. All the offspring will be normal looking but 100%
double het for BOTH lines of axanthics. The genetics are
working just fine in this example.
With co-dominant genes (i.e. spiders, pastels, etc), the same
principals apply. It is just a lot easier to produce double
morph animals if a co-dom gene is involved.
I hope this helps!
