Either you have not registered on this site yet, or you are registered but have not logged in. In either case, you will not be able to use the full functionality of this site until you have registered, and then logged in after your registration has been approved.
Registration is FREE, so please register so you can participate instead of remaining a lurker....
Please note that the information requested during registration will be used to determine your legitimacy as a participant of this site. As such, any information you provide that is determined to be false, inaccurate, misleading, or highly suspicious will result in your registration being rejected. This is designed to try to discourage as much as possible those spammers and scammers that tend to plague sites of this nature, to the detriment of all the legitimate members trying to enjoy the features this site provides for them.
Of particular importance is the REQUIREMENT that you provide your REAL full name upon registering. Sorry, but this is not like other sites where anonymity is more the rule.
Also your TRUE location is important. If the location you enter in your profile field does not match the location of your registration IP address, then your registration will be rejected. As such, I strongly urge registrants to avoid using a VPN service to register, as they are often used by spammers and scammers, and as such will be blocked when discovered when auditing new registrations.
Sorry about all these hoops to jump through, but I am quite serious about blocking spammers and scammers at the gate on this site and am doing the very best that I can to that effect. Trust me, I would rather be doing more interesting things with my time, and wouldn't be making this effort if I didn't think it was worthwhile.

There are some anomalies/defects which have been associated with the albino trait (at least the Kahl strain, I'm not sure about Sharp) - most notably with the eyes: one eye, no eyes, different sized eyes, blindness. Since it is hard to know the genetic makeup of any albino, many people are opting to outcross - breeding hets from different stock to albinos or hets - to minimize the risk. Purchasing stock from different dealers/breeders does not necessarily guarantee that you will not have problems for a variety of reasons: babies from a single clutch can be scattered across the country (gotta love the internet), so you could unknowingly end up with closely related animals; Kahl strain albinos can be traced back to a small number of initial animals; many people have taken the quick/easy route, breeding siblingXsibling (motherXson, etc).
This is not to say that one cannot breed albino X albino and get strong, healthy babies...but if even one baby ends up with a problem, the entire litter should be suspect; and serious consideration given to further breeding of that pair.

Harald stated it perfectly.
Way too many people took the fast track back at the beginning of albino boas and everyone is paying the price now. You are much better off taking your time - outcrossing - and strengthening your bloodline.

My albino females are from 3 different places as well, all good names...strong stock. But after weighing everything out, I opted to go with hypo het albino males...I didn't really want to deal with het babies, but felt it was a better option in the long run.

so what everyone is saying, (if i want to keep it small) i should have a pair of hets a pair albinos then just mix it up?

only you can decide what is right for you...depends on what you are trying to accomplish and where your priorities are. As I said, my initial goal did not include having to deal with het babies...but as I looked more longterm, I felt that I would prefer to do that than risk setbacks or weaker lines. The issue is that the eye deformities appear to be related to the albino gene, and (from what I have seen) seems to be most prevalent in albinoXalbino pairings. If I were to experience this with one of my pairings, I would feel compelled to restart my project because if there are problems with the babies it is likely to have come from the parents. That's 3-4 years down the tubes. Again, this is just my thought on the subject.

The other side of the spectrum.........
My F3 is one of the early Kahls. Bred in just such a manner. The original Kahl male, bred to a normal and produced hets....... 0.1 of these hets was later bred back to dad, and produced Aurora. She is now 7 yrs old, (this month) and has never had an unhealthy day in her life. Not one belly ache, not one bad shed, Nothing. So it is possible to have perfectly healthy babies from inbreeding as well.
Not to discredit what Harald or Mike has stated. It is very sound and good advise to line breed. I too believe in the strengthening of the gene theory, and this has slowed down My actual purchases significantly, due to Me wanting some proof of non sibling-ship. (is that even a word? LOL)
But these days, now that there has been a significant amount of breeding going on with albinos, I think the problem is pretty insignificant.
Now the problem hits the other morphs people are trying to make too quickly, like snows.
Just My $0.025

Back to the Hypo's....
OK, So I don't pretend to be a genetics pro, or even a long time breeder of morphs. I do not (any longer) question the salmon Hypo gene as being dominant.
But something about it just keeps Me thinking there is more to the salmon than mere Hypomelanism. As we know, the reduction of melanin allows for the erythrin to show through better in salmon hypos. They get redder with age.
Take a normal albino, versus a sunglow. We'll use kahl strain since that's what I am more familiar with.
A normal albino will generally loose it's red or orange with age.
A sunglow gets brighter, just like a salmon does.
Now to my feeble mind, in order for this increase in erythrin to come about, the gene would have to be affected in some way. Similar to some pastels which are concidered polygenic.
Anybody else have thoughts on this? Not trying to play evil scientist and discredit anything others have previously established, just something that has always bugged Me about this gene.
Rick
