Tangerine Albinos

[atw]

I really like the ‘tangerine albinos’ and I am interested in the genetics behind this morph.

To produce a ‘tangerine albino’ I would have to breed double hets for ‘albino’ and ‘tangerine’ to produce a small number of 'tangerine albinos' if both ‘tangerine’ and ‘albino’ were simple recessive traits; specifically, 1 in 16 would be a ‘tangerine albino’ from a double het breeding.

From the articles I have read, the production of double hets results in 'normal' looking babies if both of the traits that you are breeding for are simple recessive traits. Because ‘tangerine’ is a co-dominant trait, and 'albino' is a simple recessive trait, I think that breeding an ‘albino’ to a ‘tangerine’ would produce 50% tangerines and 50% normals that would both be het for albino. Breeding the ‘tangerines het for albino’ would produce the ‘tangerine albinos.’

Is this the case? I realize that the percentages are theoretical but do I correctly understand the theory behind the production of this morph?

Thanks,

As far as I know, and I've been breeding leos awhile now, tangerine is a line bred trait not a genetic one so there are no hets for tang. I believe that the tang albinos are also line bred.(I am not positive on this though, so don't quote me on it:D) So lets say I produce 100 albinos next year and 10 of them have a lot of tang coloration so I keep them for the following breeding season. I breed those to eachother and the following year I get babies with even more tang and hold on to the best ones again, thus continuing to breed the nicest ones. This is line breeding.

Thanks for responding. I was thinking nobody would. :)

I also found an article that helped to clarify it for me as well:

The article is quite good and explains some stuff about patternless abinos that I didn't realize either. One thing that is still a question for me, and hopefully you will know the answer, is: what's the difference between 'tangerine albino', 'hybino' and 'sunglow'?

I can see the difference between a sunglow and a tangerino albino but I don't see the difference between a tangerine albino and a hybino. As well, some people refer to sunglows as hybinos. I am confused.

Thanks,

Really, it's just degree of tangerine on the gecko. The whole hybino thing is really just "hypo albino". So basically it's the same as a hypo tang albino:D It all comes down to pigmentation. The "hybinos" and tang albinos are usually wonderfully colored, but you can tell they are albino because of the dark pigmentation of the body pattern. The sunglows are amazing in that they have very little pattern. The are like super-hypo baldie albinos. What amazing little guys they are. But, yes, they are super "hybinos".

Thanks for explaining. It makes sense now and I wonder why I didn't realize that :)

A Sunglow is a fancy marketing name created by Craig Stewart to sell even yet more Gecko's at ridiculous prices by breeding a Hypo Tangerine with an Albino.

Big deal.
