Very interesting. I posted this photo of an Opal, which I suspect may be a Blood, but many people discounted it due to some side pattern. Many Bloods do have some side pattern that are “fractured”. What a perfect description of the side pattern that I found on your link.
This Opal has a totally white belly and an odd pattern. He has been bred to a Motley and Normals were produced. He is not a Striped and I would not say that he is a Banded, so what is causing the plain belly? I guess I need to breed him to a Blood next year and find out for sure. What would be the worst thing I would get, Hets for Opal Bloods? I will not be surprised if I get Bloods het for Opal. I can easily see an Avalanche or Opal Blood getting sent out by mistake from a Het breeding. The diffused pattern is very difficult to pick up on white snakes.
It will be interesting to see how the Avalanche, Opal Bloods and Blizzard Bloods turn out as adults. Sometimes more is not better, but the genes are interesting. I personally prefer the Striped Lavs over the Striped Opals.
