Het Albino x Het Axanthic?

[ricky5042]

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

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

[DutchHerp]

50% double het

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.

[DutchHerp]

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.
