don't know much about genetics but there was a pic of a snopal for sale in the classifieds not long ago, there was quite a big difference in that and the snows i've seen. try searching the classifieds for the pic, it wasn't that long ago, it was going for 300!
everytime ive seen a snopal, it looks more of a uniform pink as a hatchling(though not always), very similar to a blizzard hatchling, but with a noticable pattern, ians sites the best to demonstrate this
snow(see white background colour)
snopal(more pink like a blizzard, but saddles more noticable than blizzard, though they are variable and some can be almost white)
My snow isnt vert pink at all really, its hard to see the saddles on her, il have to get some pics up. When she was a hatchling she was very pink with well difined saddles though, so pretty sure she is a snow, she is just very washed out now.
