As far as I could trace her back, 2 generations pure! She's actually what the island Hogs are supposed to look like naturally. The Sears line is what selective breeding can do to improve the colors and the speckling...
From Gus's site, www.riobravoreptiles.com-
Probably, few people would recognize a wild-collected Hog is. boa, if one could be found. That is because early on captive colonies of these fascinating boas began producing animals more colorful and lighter in overall tone than most anything ever seen on those humble islands. Breeders and buyers have focused on these traits and the result is an animal larger and more colorful than what was likely ever taken from the wild.
