I beg your pardon for the late reply and for starting a new thread but the old one is too difficult to survey due its structure.
I am also sorry that I took only a once over and that I don't have the time to answer to all of the postings.

My female has had 5 babies last hear. Why? Because I gave her no break after a large litter the year before. The interesting thing was that 3 babies out of 5 were Zeros.
I think this is an indication that this strain is strong.
I know the outcome of similar cases in albino boas. The worst were 26 babies from het albino parents. 25 babies were normal looking, the 26th was a stillborn albino baby. Happend in Switzerland.
This is NO isolated case! I know several similar ones. Not this bad, but approximately. But I think that this is common knowledge meanwhile.
In the light of this what do you make of the Zeros result?
Of course, this is no proof but only an indication (along with the excellent developement of the babies).
As to the Sonoran/leopard boas: The ancestors were imported in the 70ies by merchant from Frankfurt (this was before the cites). On June 6, 1979 the first litter was produced by Bernhard Gudrich from Dreieich. Hansjörg Winner got his animals from this strain and produced the leopards.
It is not my duty to defend boas that I don't even own or breed, but - dear Jeff - I know what I am talking about. I used to be an officer for 23 years and a detective for 6 years and know who to do a research and expose lies.

One of the few reasonable postings was from perfectpredators and I think I own him a reply. In my opinion he has a point. Right now there is only a harm if a purebred boa is bred to a morph in order to get something new.
The real harm was done long ago by criss-crossing different localities and subspecies like mad for the sake of creating more mutations. Furthermore the harm was done by tempting beginners to breed such boas instead of devoting their love and effort in the preservation of pure localities.

In conclusion: Field studies on boas with a transponder showed a movement of 70 Meters within 3 months. So it is safe to assume that a lot of inbreeding happens in boas in the wild. Furthermore: What about the island boas? Inbreeding occurs for thousands of years without harm there. The restriction to only a few bloodlines in some true locality boas is not an argument for crossbreeding.
Please bear with me that I can't write further replies because I have many boas to take care of, I have to update a website and write a novel.
And one thing is for sure: I will not be able to convince you and you will not convince me. So the entire thing is only entertainment and training for my bad english.
