Ok so heres what you need to know.

What the T stands for in "T" albino is Tyrosinase.

The difference between T- and T+ albino is whether or not the animal has (partially) functioning tyrosinase genes (+) or not (-). Tyrosinase is a copper-containing enzyme crucial for melanin biosynthesis, catalyzing the oxidation of tyrosine to L-DOPA and subsequent reactions that lead to melanin (color) production. 

If you just said, Huh?- no worries, Heres the differences for what it means for us as snake keepers/breeders:

T- have red irises as adults, and T+ have black irises. 

But its really hard to tell them apart visually as newborn hatchlings until you have a trained eye for it. So its always best to keep track of lineage, but even more so if you're going to work with both.

I've never noticed any difference in temperament or care between the two. So if pet ownership is what you're after, just pick whichever one pulls your heart strings you know?

There are things that are good to know for breeders planning future pairings though:

They are not compatible genes, so if you cross a visual T- albino with a visual T+ albino you will get double hets instead of visuals.

T+'s are more of a caramel color than t-'s, (tyrosinase contains copper). They tend to turn more brown or warmer toned as they age, but not by much.

I find T-s to be more saturated in color and a bit cooler toned. Excellent for retaining locality colors when outcrossing.

T+'s are the go to choice for retaining warm tones and when you dont want that extra saturation though. For example the T- hypo butter would be kinda white or practically grey, whereas the t+ hypo butter is a gorgeous shade of soft pale yellow. T+ are considerably easier to work with when doing hypo morphs too. Its pretty easy to tell a T+ hypo apart from a t+, but its impossible to tell a T- hypo apart from a light colored T-, so that's something to be aware of.

So which one is right for you as a breeder is going to strongly depend on your end goal. 

​I hope that helps :)

​We are currently working out some custom coding issues with the webhost for this page and hope to have it back up soon.

Again this is a new project so these are just my observations so far. 
It's obvious that these animals are not a typical albino, but when bred to others they are surprisingly compatible. I've done a couple crosses with them now and in every case the pairing results in babies that are brighter, more intensely colored, and with patterns that are consistently distorted, typically are either very stripey or granite speckled. In my cross to a Kzn Red Albino, I found the red was brought out immediately and rivals any other red type morph i'm currently working in. In a cross to my facemask project line it brings the white up crazy high on the sides. While it did retain some striping in each pairing so far, It only seems to retain its patternless pure white stripe when crossed to east london locality capes though. So I believe that just happens to come from that locality. So far it seems to effect both color and pattern to a degree no matter what I do with it though, so I look forward to continuing to explore it in future pairings. 

This question is asked frequently, "In many sectors of the hobby it is frowned upon or even considered "unethical" to breed hybrids. Should this attitude exist for house snake keepers?"

I think its important to keep in mind that house snake taxonomy is a mess (More on this in the popular "House Snake mess for dummies" Article). We know little about what constitutes a "pure" animal to know what constitutes an "impure" one to even explore the argument to a finality, but lets use the arguments that are common in other sectors of the hobby to explore the issue.

"Hybrids that get loose from irresponsible owners then taint the purity of wild populations"
Unless you actually live in the places these animals are native there is no risk that your "hybrid" animal will get loose and "taint" the purity of the wild strains like there is with say a specific locality of California kingsnake. So were safe there- a black house snake in africa will not be changed by yours here in the US.

"If people breed hybrids we wont have any pure animals anymore eventually. "
Black house snakes are still being exported in mass, with least concern status, so there isn't currently really a need to preserve the "purity" of every single one like there is with say blue tongue skinks where the native borders are closed, and what we have now may be all we'll ever have. So that argument also doesn't apply here like it would elsewhere either.

"Hybrids are sickly mongrels that don't do as well as their pure counterparts..."
All morphs of any animal are caused by mutation, so we have to ask ourselves where do we draw the line on this one in the first place? Is a wild caught "pure" albino cape with light sensitivity automatically healthier than a hypo green with no issues? Not in my experience. House snakes are still young in the trade, but so far I haven't come across a hybrid that lacks the health and vigor common amongst the different species. For me, that will need further exploration before Id be comfortable taking the stance that hybrids are unethical on the grounds of health. Ironically that would require more hybrids to be made in order to prove or disprove as well. I can say that some of the common morphs are hybrid crosses and most people aren't even aware of that, yet they live productive lives in captivity all the same. Butters/Illumo/hypo green are worthy examples. 

4) "People are breeding hybrids because they don't want to have to buy/wait for/breed another pure animal. Then they dump the hatchlings. "
I too think the why is important. Perhaps the most important is WHY? why does this person want to cross their animals? I've personally made several hybrid crosses and I can tell you it isn't that easy. This fact alone will weed out many of the people who will attempt hybrid pairings for the "lazy" or otherwise "less than ethical" reasons. It's a lot harder, so there's going to be a reason to endure to the point of success.
For me its to understand the boundaries of their taxonomy. Many house snakes are currently *legally* lumped together (like black house snakes and togo stripes) as the same species even though it makes no sense. "Hybrid" pairings give us information to understand these animals both here in the US and in the wild. Others may want to explore their gene plasticity or create new morphs. Point is there are perfectly valid reasons to create hybrid house snakes, and anyone that's ever seen a butter (or one's price tag) can tell you they are not being "dumped" either.  In my experience so far its been quite the opposite. I personally can not create enough of some of them to keep up with the demand for them. 

What about the localities?!
Localities with visual differences are technically not (always) *hybrids* of two species, so not exactly the same argument. They are usually two animals of the same species collected from different places (hence the term locality).  I do agree that localities should be preserved to the best of our ability (I go over that pretty in depth in my Red Kenya vs Kzn Red post if anyone is interested). I do find it unethical to claim an animal is anything its not, and especially would not label an animal as "x,y, or z" locality if you don't actually know that, because that does have the capacity to change the "purity" of that locality in captivity here over time. Even that hang up is avoid by just being honest though. There's also the very valid argument to be made that even the localities that we do "breed pure" will not stay the same as those in the wild over time, since we will be selectively breeding those towards the traits we breeders like, resulting in differences over a long enough scale of time. But again that's another subject than strictly *hybrids*. 

So we should just take peoples word?
Some will say that you shouldn't expect people to be honest and sure that's true, but you certainly can say that about every aspect of life- that's not new here. The best thing to do is to research the traits of the morph, specie, or locality your interested in and of course research the breeder you intend to buy from. 
​
Long story short
if you honestly represent the animals you have made as hybrids, so that everyone knows exactly what they are getting, I just don't see the kind of reasons to devalue or snub hybrid house snakes like there is in other types of animals in the hobby.

Lastly, It is ok to agree to disagree. 
Hybrids aren't for everyone. Some people don't like the idea of animals having any type of mutation at all. That's ok! You can like hybrids or not. You can like mutations "morphs" or not. One of the best features of this hobby is that were all a little misfit in the first place, so there's no reason we cant respect each others differences. :) 

M2 has the faded pattern and eye stripes  of a kzn red but slight black rings and the warmer tone of red kenyas

M3 has faint black eye rings, solid eyes, and eye stripes that are closer together like the red kenya but with some parallel striping and pattern fading into the body like the KZN red does.

Based on these and the rest of the clutch I feel its safe to say that these two localities are fairly compatible despite their taxonomic differences (kzn red are a capensis and red kenya are fuliginosis).  At the time of breeding them it was my hope to 1) see how the traits combine to further understand their differences and 2) be born with and continue to develop in time a nice deep red color.  Time will tell :) ​

Cape crosses tend to take after their cape parents in most house snake pairings and it is no different in Reds.
​
Both of the following animals have Kzn Red Blood. The first (stretched out) was produced by breeding a pure kzn red to an Albino cape. Note the high amount of pattern present when compared the the pure kzn red hatchling pictured next. 

In the next pictures a Red Kenya was bred to a Cape Albino then those babies were bred back to siblings. Ive noticed the base color of the red retains its warmer color and the eyestripes still are a touch yellow and touch at the nose on these pairings.

Even in their second and third generation I find differences. In RK albino I notice a fair amount less pattern the higher the blood concentration is RK. In KZN Reds I find you can push the red in the pattern higher, but not the base, resulting in higher contrast hatchlings. 

Naturally, I'm always thinking of new ideas and ways to make even more stunning babies. There isnt many morphs of these yet but I will be updating with pictures of morph babies of both as I create them. Feel free to share your experiences as well!​
