Het Albino x Het Axanthic?

Hi what would or could i expect from matting my 100% het Aldino male to my
100% het Axanthic female
Thanks

Rick

25% normal
25% het axanthic
25% het albino
25% het axanthic het albino

*EDIT* All normal appearing offspring, So I'm not sure how you'd put that... probably 66% possible het for either...? Not sure.

50% double het

Hi would any of the hets come out lighter or have any markers than the normals so i could id them or would it be guess work to id them

Why? Only 25% would be double het... Can you explain?

Not really.

Nope.

And chances of finding the right ones to pair up would be a total crap shoot, being that a double het offspring bred back to the single het parent, will only produce the recessive trait in that parent.

You would need to breed the offspring to each other.

Double hets bred to each other, you may get a double homozygous recessive... but a double het recessive bred to a normal offspring will give you possible hets (but you would not know by looking at them).

Each snake is 50% het albino 50% het axanthic. Most people just write "poss. double het"

But you are right, its not 50% chance that its a double het, just for each one of the traits.

Basically breeding double hets to eachother will give you a 1/16 chance to have double homozygous offspring.

Yes, these percentages are absolutely correct except that for pos hets, there would be a 75% chance that the offspring are het for something. Accounting for all possibilities, and because they all will appear normal, it would be correct to market them as 50% PH albino, 50% PH axanthic, and 25% pos double het in the overlap.

Thanks all for your replies
im getting a male and female 100% het Axanthics in a couple of weeks brother and sister would it be ok to breed them and what chance of a visual Axanthic?

Rick

You'd get a 25% chance of getting a visual. Hopefully, the Mendelian gods will smile upon you. Heaven knows we've had disappointing seasons where we did not get visuals. And, then there are some lucky folks who get far greater than 25% success. Good luck! Axanthics are beautiful.

Thanks i hope i do get a visual Axanthic cos for sure i couldnt afford to buy one
il be happy with just 1 for my personel collection

Each snake has 50% chance of being het albino and axanthic, therefore they are 50% double hets....not 50% of the clutch would be double het

That is the way to go if you want to produce an axanthic. :gj:

Streamline it and work with what is your priority. Otherwise you can invest a lot of time and money and not produce what you want.

100% hets bred to each other give you... in a clutch of four.

1 axanthic
1 normal
2 66% possible hets

You hold back all the daughters and breed them back to dad and in produce more the next season. :)

Good luck with the project. I really like Axanthics, I think they are a must have in any collection.

And yes, parents bred to offspring and siblings bred to each other is fine.

If you do decide to go for the possibly quicker but less sure route to snows by breeding the het albino to the het axanthic then you could keep back all the female possible double hets and buy an unrelated for sure double het male (careful of compatibility on the axanthic line) to breed them to. Still a long multi generational project with no assurance you will even have the double het pair to get the 1:16 shot at snow eventually. But I'm doing worse, I'm breeding a possible double het male to a possible het albino female.

what would this produce and how far would this be from a snow LoL thanks guys and girls :)

A Genetic breeding nightmare, lol.

lol

My breeding or the original het X het?

If you have the money by all means get a pair of snows (seems like I saw a pair on KS for 5 or 6K) and remove all doubt by producing 100% snow clutches.

I like the fun of breeding possible hets. In 2003 I bred possible double het snow to possible het albino and in two surviving eggs had two albinos. But I did something wrong (most likely treating infertile eggs in the same clutch with foot powder) and they where both kinked so I never got to find out if they where also het axanthic. But that's what I'm hoping for this year, some keeper albinos with a shot at having something extra.

Wild pythons have a limited range and therefore a shallow gene pool, so inbreeding does occur. VPI asserts that inbreeding snakes in captivity increases the likelihood of expression of recessive traits, both desirable traits and deleterious traits, and that inbreeding has produced snakes with problems. Formal studies are lacking, and the ball python genome has not been sequenced yet. Veterinary care for herps is not as advanced as it is in other species, and as you know, compromised snakes often hide their infirmities quite well. A study of melanistic garter snakes in 1997 by J. Chelebowy proposed that degenerative effects are caused by increasing inbreeding. It has been suggested by some breeders that tail kinks in caramels and head wobble in spiders may be a result of increased inbreeding. IF this is indeed the cause and effect then perhaps these abnormalities may confer a selective disadvantage in the wild, though animals with these abnormalities that are properly housed and fed in captivity without predation do just fine. Though snakes appear to be highly tolerant of inbreeding, it would be my advice to do it when you need to and avoid it when you can.

This. I'd rather work with say a 50% DHet Snow and a 100% DHet rather than two 100% Hets bred together. That's a lot of normal looking babies to hold back. In the long run you might as well buy a pair of Double Hets, or heck make your own pair!

It is getting to the point where more and more people can afford visuals and for sure double hets. I would rather be using a for sure double het myself and was in the process of buying a near breeding size double het albino pied male for $200 but the breeder lost him in an accident before the exchange so I settled for a $100 possible double het breeder. I don't think double het males can regularly be had that cheap and would expect double het females to be much more expensive. I'm only planning to hold back select females (either visuals or at least well marked in the case of possible het pieds and perhaps possible het stripes). The out right snow pair would be out of most people's reach still so we all make due with the best we can afford.
