Vascular Patterns

Yes, that's exactly what happened in my experiments with the arilbreds.  As it
stained the vascular system, the food coloring clearly revealed the vascular
pattern.  There were several distinctively different patterns, but because they
did not correlate with pigmentation patterns I'm still trying to figure out
their significance, if any.

So this raises another question -- is there really  only one vascular pattern in
TBs?
