There are no varieties that call specifically for it, but because of the way the neural crest develops in relation to color, a lot of varieties have a white stripe, which is counted as a fault.
I'm not the best with remembering the marked varieties, but there's one in particular that I've seen a lot of poor examples with white stripes that go straight down the spine. I'm pretty sure it's variegated.
That sounds familiar!
Do either of you know where I can see some pictures of it?
I knew a 'head spot' is considered a fault in a few patterns (and I've seen it go as far back as the middle of the spine from the forehead), but I just didn't know if there was something that specifically produces those stripes, or what. If Variegated can create that effect, I'd love to see some photos of it.
