Does a het to het cross just give you all hets? or do u get half of the babies are hets and the other half are actually homozygous?

All per egg:
50% possibility of heterozygous form.
25% possibility of homozygous form.
25% possibility non-carrier.

So the non carrier would never produce antyhing but normals even bred to a homozygous partner? thats crazy that it works that way.:confused:

Yes. All per egg, not per clutch.
Here's an example:
Consider the scenario that someone is selling snakes that are all possibly het for a recessive trait. They could all be het, or they could all be non-carriers.

Every egg from that pairing would be het.

Here's another example:
Normal, or any morph that's not albino X albino = all eggs het. for albino.

Oh so out of 4 eggs you would typically have one hatchling who showed the trait (albino..pied, ect..) and 3 that either were all 3 hets, or all 3 that were non carriers... correct? But not one that showed the trait, one that didnt carry and 2 that were hets?

For the example of het X het, no. The clutch could be any combination of homozygous, heterozygous, or non-carrier. They could even be all homozygous, all het, or all non-carrier.

...OR you could get something completely different because the dam retained sperm from a prior pairing to a different male with different genes.
