I don't view Hoggs as being a morph. I think they represent the result of evolution similar to the destinct pattern of a Peruviam boa. What is very interesting is how the hypomelanistic phenotype is so common in these boas that come from small islands. From the boas I have seen this group shows the most dramatic abilty to color change. I think this phenotype and color change ability likely reflects the fact that these boas probably move through and exist in more diverse environments than a boa that is born and lives within the jungle for it's entire life. I think this is why these boas from small islands show varying degrees of "natural" hypomelanism.
Regarding sunsets and other hypo crosses what I think is interesting is that both salmons and Hoggs have the ability for dramatic color change. I don't know if the genetic basis for this is the same in both animals. In crosses which have a variable amount of either animals' genetics this color change ability can manifest itself in both a dramtic appearing animal and a range of ability to color change. I think this is part of the beauty of the sunset boa. Perhaps someone with other Hogg crosses can tell us how much a surinamxHogg or Peruvian x Hogg can color change.
