Well hets are simple. I'll use albino as an example.

Normal x albino = normal babies all 100% het albino

100% het albino x normal = normal babies 50% het albino. (means approx 50% of the babies will be het for albino)

50% het albino x 100% het albino = all normals will be 66% het albino. Course if u get albino babies you've proven the 50% to be 100%

Correct me if I'm wrong but I think this is right.

That's wrong.

Using albino as the recessive in question..

Albino X normal = all hatchlings are 100% het albino

Het Albino X normal = all hatchlings had a 50% chance of inheriting the albino gene, hence, 50% possible het

Het Albino X Het Albino = all hatchlings had a 66% chance of inheriting the albino gene, hence, 66% possible het

When breeding a 100% het to a possible het, be it 50% or 66% possible het, the hatchlings would be considered 50% possible hets, unless of course a homozygous recessive is produced, which would then make the hatchlings 66% possible hets.

ok so if i get a 50% het raptor then when i breed him/her 1/2 the babies will be raptors and the others will be what ever i bred him to? is this correct

The 50% means that there is a 50/50 chance that the leo is het for some or all RAPTOR traits, so you might not get RAPTORS at all. It also would depend on what you're breeding the poss. het RAPTOR to. Breed even a 100% het RAPTOR to a normal, and you won't get RAPTORS.

So, theoretically, if you bred a poss het to a poss het...what's the percentage of het possibility for the offspring?

ahh statistics. gotta love it. if u breed a 50% possible het to another 50% possible het the resulting offspring would be 25% possible het. for two instances to happen at once you multiply the likelihoods of them together. ie 50% x 50% = 25 %

Correct. Possible hets should ALWAYS be disclosed, even if it is a low probability. It would be even better if people took the time to prove their breeders before using them for a project.

I completely disagree with this way of thinking. If two 50% poss. hets are bred together and there are no visual (homozygous) morphs are produced, then neither has been proven as a het, so how can you sell them as possible hets?
I do understand that based on odds, there are possibilities for the genes to be passed along without the "hets" first being proven out, but to call these offspring 25% possible hets is completely misleading. The reason for percentages in relation to possible hets comes from the chance that each egg has of inheriting the gene,...i.e. het X non-het=all eggs have a 50% chance of inheriting the gene,..or,...het X het=all eggs have a 66% chance of inheriting the gene. Ultimately, percentages mean nothing until a het is proven or not, at which point, the animal is either het or it is not.
What's next? 12.5% possible hets? Anything to add a few bucks to the selling price I suppose.

You may not agree, but he is right. It isn't about charging extra, it's about disclosing the genetics of the animals you're selling. A known non-het is not the same thing as a "probably not het but I'm too lazy to prove my breeders." Some geckos are worth more without any hets, and you're saying it's ok to sell them that way? I know I would be very unhappy if I purchased an Eclipse with no hets only to find out the parents were possible het albino but the breeder sold them as clean because he/she didn't want to prove them.

While obviously saying 12.5% het is ridiculous, saying Possible het is not. Saying possible het from my point of view does not add any value to selling the gecko it advises the customer that there is a small chance that these genes are in that gecko you are buying. I look at it in the interest of full disclosure. Does this matter to a person purchasing a pet? No, it matters to a breeder who wants to know exactly what is in the animal and that is the responsibility of the breeder.
