I have always been curious what the BCI and BCC world think of this question:

The Wife and have talked about this before and we have discussed this on other forums, but Say for example, Some one breeds a (Hypo x Hog) or a (Hypo Bci x BCC) and then they take the offspring and breed it back to one or the other example:

Breed the offspring of a Hypo x Surinam back to a Surinam, and keep doing so for 5 or more generations, will there be a point where someone could classify it as a pure Hypo Surinam?

Example: Hypo bci x Surinam BCC = 50% Hypo Surinam

50% Hypo Surinam x Surinam = 75% Hypo Surinam

75% Hypo Surinam x Surinam = 88% Hypo Surinam

88% Hypo Surinam x Surinam = 90something%

and after the 5th or 6th time, they would be pretty much Pure Surinam correct or do you think that becuase it has the hypo gene it will never be a pure surinam? Just curious how the BCI and BCC world looked at this?

Isnt that more or less the case with the hypo Columbian boa? I think they still have central american blood way back in the wood pile dont they? If this is true.... and they have been outbred so much they are considered Col. hypos.... the same would be true of a BCC outbred 6 generations.. just a thought..Dan

Of course you'd probably get some that would argue to the contrary. But to me, pure = 100%. No matter how many breedings, you'd never reach 100% with your example. You could get to 99.99999999999999999999999999999999999999999%, but you'd still never be at 100%.

The problem comes in when some people start making their own rules. For example, the suri x col albinos. I've seen on the classifieds people offering "suriname albinos" but they're obviously not, to someone w/ an educated eye or knowledge of the history of the species and the market. But what about the novice hobbyist who happens to be looking to drop a decent amount of money on an initial pair of animals. They've seen albinos, they've seen surinames, but they've heard that suriname albinos are very rare. Well, they see someone offering them and decide to purchase them and never ask (because they assume complete honesty) or are never told they're not pure. They keep these animals for a few years never learning any better and produce some babies and begin to sell them. This happens right around the time that there IS some success w/ the pure suriname albino and now we've got an arguing match as well as distrust and possibly some ruined reputations. I guess the point is that no matter how pure a person thinks something is, they should refrain from calling it pure unless it's 100% w/ no rounding.

Hypo "Colombians" started as Panamanian/C.A. Hypos. No one questions a Hypo called Colombian Hypo, even though it is NOT.

With the recent 88.5% Salmontines I would love to see a male from that litter bred to an Argentine T-positive, then breeding a DH male that is in the 90% range back to an Argentine T-plus. They are NEARLY pure. Maybe more so than many "Colombian Hypos".

However, just to be clear, it should be noted the percentages, or at least the origin of the starting mutation.

It goes allong with the Suriname X Colombian Albinos. There are 75% hets, and there are some 50% Albinos that look like Surinames. But they shouldn't be sold as Suriname Albinos, because there are REAL Suriname Albinos.
I've seen Argentine X Albinos sold as Argentine Albinos, people might get them for their pure Argentine group not knowing (a new guy). Conversely I've seen more and more of them sold as Bubblegum Albinos, or Bubblegum Corals to describe the pink color commonly seen in them. Someone may buy one thinking it is a special form of Albino and breed it thinking it is just a different Colombian morph, not knowing it is a cross.

I see no problem in crosses, as long as the information is recorded, kept, and provided with every animal.

you might think you have one that looks like 100% suriname, but I bet you I could still spot those colombian traits in there, even after 25 generations. Here's why. A suriname look is made up of many many traits. If you choose for say 5 traits you think are suri traits, you will be in fact deselecting for the other 20 you don't happen to be aware of. Eventually all you will get is a "suri" with only the 5 traits you decided to select for. Someone else will come along looking for one of those suri traits you missed and didn't select for. They will see your animals as crosses instantly. You can't select for every trait when there are a bunch of them, some babies will get some and other babies others.

Good luck selecting for all the suri traits at once in each individual holdback, my friends!
