What I DO remember from that session is finding out that a signal is more
than just a "spot pattern", that the plant cells in the signal are
elongated,
which gives some kind of texture rather than just color. I had to run out
to
my garden when I got back to do some signal v. spot differentiating! That
was interesting.

True, as far as it goes -- but ASI's rules recognize both the onco-type
textured signal spot and the simpler spot pattern that appears to be
inherited from I. korolkowii.
In many oncos and in some of the 3/4-breds derived from those species, the
velvety texture of the signal area can be detected by simply running a
finger gently across the area. Close your eyes and do the same to most
halfbreds and quarterbreds with signal spots, and you'll be hardpressed to
tell where the signal area begins & ends unless you have the trained
fingers of a safecracker!
In halfbreds and quarterbreds, the spot that used to be called a "signal
patch" is much more common that a true, textured signal -- and is still
classified as an acceptable "aril trait".
