Ok, now that I'm getting this het albino retic, and hopefully either another normal het or tiger het albino in the nearish future, I have some questions. I've been told that there are three different color variations on the albino trait in retics: white phase, lavendar, then purple. I've also been told that all three of these varieties can occur in the same clutch. Some people I've spoken with though seem to think that certain strains tend to produce only or mostly that same strain. My being a fan of the lavendars and purples over the white phases (too much like an albino burm to me...lol), am thinking that if this is the case, should I be sure to get another het produced from a lavendar or purple to normal breeding? Or does it not matter and I'm going to get all colors potentially anyway? Keeping in mind here, I realize genetics is never set in stone so even from breeding two 100% hets together there is no absolute guarantee I'm going to get albinos, much less the color of albino I want, I'm just looking for statistics here.

Ok, next is about tiger hets. Let's say I were to get a tiger retic het for albino. Tiger is a codom trait right? So when breeding a tiger to a normal you usually get 50% tigers and 50% normals? So, if I were to breed a tiger het albino to a normal het albino, what are the possibilities of getting: A. normal 66% possible hets, B. albino normals, C. tiger 66% possible hets, and D. tiger albinos? If there are other possibilities in this scenario, by all means let me know. These are just the ones I can think of.

And lastly, I think super is a trait that is recessive like albino right? (Correct me if I'm wrong here) So if you breed, let's say, an albino either normal or tiger, what are you going to get? I'm guessing with a normal all the babies would be het for super (??) and het for albino. However, I have no idea what the outcome is with breeding a tiger to a super.

Anyway, that's it I suppose. Having all these different morphs to play with is just fun, and although cornsnakes are alright, retics are just a tad more exciting and interesting, lol. Thanks to anyone who replies.

I am only going to touch on one aspect of the above questions because I just woke up and therefore am not mentally awake enough to go into all the genetics but you have one obvious fault in yourthoughts above. Tiger isn't a co-dominate. It is a dominate gene. Meaning that it only needs to receive the gene from one of it's parents which is why you can receive the trait by breedinga tiger with a normal. A suoer tiger is a co dominate trait. It is the result of breeding either a tiger to tiger, a tiger to supertiger, or a super tiger to a supertiger. This morph is the result of the baby receiveng the tiger trait from both of its parents. Hope this helps a little. I will check back later and if no one has answered the rest of your questions I will give it a try for you, Todd

Alright I woke up some more and I figured I would answer the other part of your question. As far as the different color morphs I honastly can not answer this question but in regards to the question about breeding a Retic that is het for albino with a tiger retic that is het for albino the offspring should be as follows:
12.5% Normal Retics
25% Retics Het for albino
12.5% Albino Retics
12.5% tiger retics
25% Tiger Retics Het for albino
12.5% albino Tiger Retics

That is the breakdown of the offspring. However you should note that it will be impossible to tell the difference between the normal retics and the retics het for albino as well as the tiger retics and the tiger retics that are het for albino. So as far as I can figure out you would have to advertise and sell those as 50% possible het for albino. There is a pretty good site that has a getic wizard that helps you figure out all these traits. It is www.geneticswizard.com. It will allow you to figure out up to six different genes so it can be pretty helpful with some of the tricky ones. Just remember that tiger for example is a dominate trait and therefore must be assigned as a dominate gene but since it only carries one gene then you must also check the het box or else the calculations will be off. Hope this helps some more, Todd

I must make one correction. I wasn't looking at my figures correctly when I stated that the hets would be 50%. They would actually be 66% het since 2/3rds of the offspring would be het. Sorry for the erroneous information. I hopes this helps out, Todd

I was thinking they'd be 66%'s, not 50...thanks for correcting that because you have me thoroughly confused, lol. I also realize that all the normals and hets will look just alike and I'd never advertise something incorrectly.

So tiger is a dominant trait. Does that mean when bred with a normal they still produce 50/50 tigers and normals, or would they produce all tigers? And if super is codominant, when bred to a normal do they produce any supers or just all het for super? Sorry for all the questions and I don't mean to be confusing, I'm just trying to understand all this complicated mess.

I am sorry about the confusion earlier. You are correct that if you breed a tiger to a normal you will produce 50% tiger's and 50% normals. Also if you breed a supertiger to a normal you would get all tigers. I wouldn't use the term for het for super because that basically is just describing a tiger retic. Let continue on with this for a second and see if I can get to your questions before you ask them. If you breed a tiger to a tiger you will get 25% tiger and 50% supertiger and 25% normal. Breeding a supertiger to a tiger would result in 50% tiger and 50 % supertiger, and supertiger to supertiger will result in all supertigers. Hope this helps out some more, Todd

Super tiger is the homozygous condition of the tiger gene. Normal is the homozygous condition of the typical gene. Tiger is the heterozygous condition i.e. one normal allele and one tiger allele. This heterozygous condition produces a phenotype that includes BOTH normal and super tiger characteristics combined (tiger). This IS the genetics definition of co-dominance. Some could argue for incomplete dominance, but simply dominant to normal it is NOT.
