is the white Isabel trait a recessive gentic trait? also, are there any other color or pattern morphs that we know of?

I don't *think* the Isabels are considered a morph, just another color variant of the SIGB's. I read in that Reptiles article from 98 that there was a hypo that Jerry Conway had, but I don't know if he still has it or what the deal on it proved to be. I believe I saw something on the forums that he had found a new morph of Candoia, but I don't know what it was/is. You may want to email him and ask if there are any Candoia morphs available. That's where I would start.

Raven is correct. The "Isabels" are a term used to describe the white SIGBs. There does seem to be some genetics involved as you get some of the other colors from a pair of white adults but mostly white babies. But when you breed a white to another color you usually get 50% or less, usually less, white. The specimen that Jerry Conway has is not a true hypo. It was a fully colored white and red male that lost it's color over a period of several sheds of skin. No hypos have been able to be produced from this individule specimen. I have heard of albino SIGBs in Canada but I have yet to see it with my own eyes. I have seen white with yellow zig zags, but the eyes had normal color. Hope this helps.

how long has he had the leusistic one? has he bred it yet?

If you are refering to the boa that lost a lot, but not all, of its red after several sheds, he has had it for several years. Again, it is not hypo or leucistic. It is really more of a freak of nature. It was a perfectly normal white male with a red zig zag and other red markings and after several sheds, it lost the red zig zag and only has a few red markings on various parts of its body. No hypos or leucistics or any other morphs have been developed from the breeding of this male. It was just something really weird that happened. It is a beautiful snake, but nothing genetic has been able to be proven yet.

This info is correct leucistic are born white
