66 % het axanthic or not

We bought two normal female ball pythons off a breeder ,and when we bought them we thought their pattern was way different than the standard normal ball python. Talking to the guy we bought them from he said they were possible 66 % het axanthic. Being new to this we are not quite sure what we are looking for or what morph we would have to breed her with to prove her out if she is het.

Reading the post on het axanthics (http://www.ball-pythons.net/forums/s...t-Red-Axanthic) we see most of the traits listed but not all. I will post pictures of her and I hope someone more experienced will be able to tell us if we have a good chance of her being a het or not.

Thanks :)

Welcome to BP.net!

Do you think these females might be Het Axanthic or Het Red Axanthic? Your post says one thing, but your link says another.

With possible Hets, the only sure fire way to know that they are Hets, is to breed them and prove them out.

Thanks :)

They might be Het Red Axanthic. Sorry not sure how I missed "red" when I was typing it out. Thanks for bringing my attention to it

Axanthic and Het Red Axanthic are two different morph.

One is recessive the Axanthic the other is Co-Dominant Het Red Axanthic.

Since he mentioned it was 66% Het Axanthic he was in fact talking about a Axanthic in this case the parents were both Het Axanthic.

There is no 66% Het red axanthic, an offspring will either be a Het Red Axanthic or be a normal since this is a Co-dom gene.

I agree w/ Deborah. Het Axanthic and Het Red Axanthic are completely different morphs. And the fact that the breeder mentioned that the snakes are 66% hets (which is a term used for possible hets for a recessive morph), he surely meant its het for axanthic and not for red axanthic.

Thank you both for your reply. Please excuse my inexperience I don't mean to say you are incorrect just trying to understand if the information I have read is wrong. The Hunters guide says
" Incomplete Dominant (Co- Dominant ) A Het Red Axanthic (HRA for the rest of the article) breed to a normal will produce 50% HRAs and 50% Normals. A HRA breed to a HRA will produce 25% Red Axanthics / 50% HRAs / 25% Normals."

Wouldnt the HRA & HRA give you a 66% het HRA? Because there is a chance the snake could be one of the 25% normal or one of the 50% HRA. Or what would that be called?

Thanks again this has all been extremely helpful.

No - because het-red is VISUALLY identifiable from normal. I think your breeder meant regular axanthic rather than het-red axanthic. They are completely different morphs.

*edit i see you understand this part*

There is zero reason to call a het red axanthic 66%, so you were mistaken or lied to.

Thanks for all the replies. We purchased them as normal females so no biggie if they are nothing more. He didn't tell us till after the fact that they were 66% het red axanthic. He might have said 66% het axanthic and in my google quest I added the red seeing the "markers" sorta match. Just seemed like a shame to breed them to our normal male and dilute the percentage, if any.

Thanks for all the information, everyone has been super helpful :)

As others have pointed out almost surely not "red" axanthic as the hets are visible so no possible het percentage. You posted the percentages expected for each egg but once the egg hatches you know if you hit or not by looking at co-dominant mutations.

However, I would try to get ahold of the breeder and find out which recessive axanthic line he was talking about. Also, confirm that both parents where indeed 100% het (where there any visual homozygous axanthics in the clutch?). Because there are at least 3 (four if you count the new black axanthic) incompatible recessive axanthic lines you would need to know which to breed them to. For any of those (with the possible exception of black axanthic) you could pick up a 100% het male of the same line for very little and at least have the chance of producing some axanthic babies.
