Albinos

I am a little confused about the Albino gene. Am I correct in that there is an Albino, Caramel Albino and Lavender Albino gene and they are all DIFFERENT from each other? I am trying to understand how they interact with each other.

For example: What would I get if I bred a Het Caramel Albino with a Pastel het caramel albino?
What would happen if it were a Pastel het Albino or Pastel het Lavender Albino instead?

I am familiar with how recessive genes basically work, but the Albino part is throwing me for a loop. Any genetics gurus out there I would appreciate the help:D
Thanks

(I chose the examples above because I have some of those options open to me)

Unfortunatly i suck with genetics, im trying to learn it all myself. so i will be watching for the answer :)

pastel het albinoX pastel het caramel albino = pastel double het albino/caramel albino.... Does that make sense ?

Are there books out there on genetics of ball pythons haha

You would get Pastel Caramel Albinos, Caramel Albinos, Pastels poss Het Caramel Albino, Normals poss het Caramel Albino. (Poss meaning they could be normal)

More confusing...

You would get double possible hets of Caramel Albino and Albino or Lavendar Albino... Depending on what combo you are asking about.

Oops i read the ? wrong :oops:

Thanks Heather, that actually clears up a lot for me, I can now go and figure out Punnett squares for what I could get. The double-het makes sense to me seeing as they are different genes.

No problem :) :gj:

Now my brain hurts:D

I'm pretty sure I set-up my Punnett wrong. I thought I had it, but I do not get any Pastel het Albino Caramels in my calculations. How many total combinations should there be(including duplicates)? Or another way of asking would be, how many squares should my diagram be? I'd love to be able to figure this one out before anyone gives me the actual percentages(or before I go to the looney bin).

I think it will be 16 squares. Just wait till you get to triple morphs! :weirdface

It's generally assumed that the following are mutations of different genes:

1. Albino (aka "regular" albino)
2. Caramel (aka Xanthic)
3. Lavender Albino

I know RDR has done and reported the breeding to test at least one and maybe two of these. I believe I've heard reliable reports that regular albino X lavender produces normal looking double hets and the same for caramel X lavender.

However, I'm not aware of anyone reporting having breed regular albino X caramel to test those two yet. There are actually some old results of an imported caramel producing regular albinos. The accepted explanation was that the imported caramel was also het albino. However, an alternate explanation could be that regular albino and caramel are alleles, different mutant versions of the same gene. The best way to get to the bottom of which explanation is right will be when someone breeds a regular albino to a caramel and reports if they get the expected normal looking double hets or perhaps all somewhat caramel looking albino||caramel offspring.

Great stuff Randy, thanks. I'm really starting to enjoy learning about this. Now let me throw another twist into it if you don't mind. How does the Caramel gene relate to the Caramel Albino gene? Are they only the same in name? If I had a caramel or het caramel and bred it to the het caramel albino what would happen? A similar question to the original - is the Caramel gene different from the Caramel Albino and crossing them would get you double hets of Caramel Albino/Caramel? or would the 2 caramels somehow interact F1.

p.s. I got myself so confused with the Punnett squares that I can't even do simple ones at the moment:rolleye2: Could anyone give me the combinations/% of each offspring from a het caramel albino X Pastel het caramel albino.

I hadn't noticed caramel and caramel albino being used separately. I think it just depends on how much the person wants to write. I believe caramel, caramel albino, xanthic, and probably even xanthic albino (can't remember for sure but might have seen that one) are all different names for the same mutation.

Now, that being said I do think there are some new lines called caramel that might be different mutations all together that just happen to look some what like the established caramels and need a new name and maybe one has been given to them already and I'm just behind.

My question is has anybody bred to double het caramel albino x lavendar abino or abino to date and if so would it have any effect or because it's on the same chromosome would it not make any difference it'd be one or the other. Or lethal combination?

Here's a fantastic link for you done by our very own Judy (JLC). It's a sticky in the Ball Python Morphs & Genetics area of BPNet. :)

At the end of it you'll find some great links for further study and help to understand the complexities of their genetic potential.
