I have a question on genetics and law. I have a male Argentine/Columbian and a Female (not related) Argentine/ Columbian that I’m going to breed. Is the Argentine darker pattern dominant or co-dormant, and if it’s co-dormant should I yield 25% Argentine look a likes? I assume I wouldn’t need any special permits because they are technically not pure.

Thanks!

They're hybrids. Morphology seems to be irrelevant here. Unless I'm missing something....which happens ALL the time.

Sorry for the silly question, I’m just getting back into Boas, my expertise is with Carpet Pythons, Balls and Bloods. As far as the legal stuff, I didn’t think Argentine Boas were a problem but my brother sent me a Boa care sheet from Melissa Kaplan's Herp Care Collection sheet, and it said,” All of the Boa ssp. are listed as threatened on Appendix II of the Convention on the International Trade in Endangered Species (CITES); the Argentine Boa (B. c. occidentalis) is on Appendix I--the endangered listing. Appendix II animals can be exported and imported with the proper permits, and can legally be sold through the pet trade; Appendix I animals require special permits to buy, sell, trade and own.” I assumed this doesn’t apply to sales and ownership within the US., but I was not sure.

That right! Brain fart! Hybrids don’t work that way. I should know by my dealings with Carpet python hybrids! All you get is varying degrees of homogenization. I’m sure some will look more like one or the other.

Thanks!

The Argentine pattern/coloration isn't a morph, and therefore is neither dominant or co-dominant. Argentines and Columbians are different subspecies, and the babies appearance will be somewhere between a Columbian and an Argentine, in other words the babies will look like your adult crosses. As for permits, it depends on what country you live in, but in the US you don't need any permits to keep Argentines.

Argentine boas can be kept, bred, sold, and shipped anywhere in the U.S. without any permits because they are not covered under the Endangered Species Act. The only time you would ever need permits would be if they were to be shipped out of the country, or received from another country, because they are covered under CITES Appendix I.
