2 hets do what?

i see alot of ppl with normals that are heterozygous for whatever morph? so does this mean if i put two hets that are 100% will i get the desired het baby? i am still trying to get and idea of what kind of snakes turn into what when crossed... do any breeding programs use backcrosses or use incest mating to keep a certain gene? thanks for any help....j.p.:confused:

Well snakes do not "turn in to" anything :)

If I am reading you correct you are asking what the progeny of a het x het breeding would be (assuming the animals are both het for the same trait.)

So to make it easy I will just use albino.

het albino x het albino will give rise to:

albino (1:4 odds)
het albino (1:2 odds)
normal (1:4 odds)

The hets and the normals will look the same though, so any given normal looking baby from the litter grabbed at random will have a 1:3 chance of being a het.

And yes, line breeding is common

Here's some links that should help you understand ball python genetics.

Actually each normal looking baby would have a 2/3 chance of being a het.

Yes you are right. I meant to type 2:3 damn my clumsy fingers.

:rofl: I figured.

you guys are awesome! that was exactly what i wanted to know. i am looking at purchasing some poss het albino from 8ball. i am still looking for the "best deal" but i want quality as well. thanks alot for all your help..:banana:

One of the biggest things when it comes to purchasing hets is to go with a reputable breeder. You are buying into that rep when you purchase genetics you can't visibly see, like in the case of recessive hets. Adam from 8Ball has one of the VERY best reputations out there so I would tell you to buy with absolute confidence. I have a number of snakes in our collection from Adam and they are all just fantastic animals. His genetics paperwork that accompanies each snake is highly professional and very complete. :)

Be sure you understand the percentages and the term "possible het" or "probable het". You'll see 50% probable hets, 66% probable hets, and 100% probable hets. A 66% probable het has a 2/3 chance of being a het, and a 1/3 chance that it is not. It either is or it isn't. A 100% probable het is advertised to be a het with NO chance that it isn't.

You MUST be careful who you buy hets from. Since they look normal, its easy to sell a normal as a het.

All that said, you mentioned 8ball. You can be very confident that you are getting what you pay for from Adam at 8ball. (edit) You beat me to it Jo! ;) (end edit)

There is not such thing as a 100% probable :) When probability hits 1 it is a certainty, all chance removed.
