not a genetics expert, but i'll field this one. Two hets for same trait will give you one showing the trait, two hets, and one neither (normal) out of four. Good luck telling the two hets from the normal. As far as albinos go, depends on the type of albino, but if they are both the same kind, you will get the same results as above.

I acually had a question also.
Does anyone know if there is a limit to which of the Fat-tailed breeds can you inter-mix? I have a young leo that I'm not sure what it is yet. I think it is a Carrot, possibly with a Circle Back. I also have a African Fat-tailed, which is dark brown and light brown bands. They are both fat-tails, but I haven't heard much about the African's on this site. Do you think they can breed? Also, even if they can't if this new one turns out to be a girl, do you think they can live together.. Once she is fully grown of course. I'm just not sure if the derastic color difference would matter. I guess it might just depend on their oppinions.

You can't breed an African Fattail (Hemitheconyx caudicinctus) Gecko to a Leopard(Eublepharis macularius)Gecko, 2 different species.
They also have different husbandry requirements, so no you shouldn't house them together.
Before you even think about breeding, you should take the time to learn more about the lizards you already have and what care they need....

say you have 6 cluthces of 2 (12 geckos), from the showings of a punic square you will have 2 pure albinos, 1 het for the trait, and 1 new morph(the one they are both het for), so the chances of getting them is 1/4 meaning you will probably have 9 albinos and 3 new ones.

I'm not sure what question you are answering, but the answer you gave doesn't match either of the 2 scenarios he gave.
1- He asked what a het to het would produce, which would give him a 25% chance of Albino, 50% chance of a het and 25% chance of normal on each egg, regardless of clutch size.
2- His second question was what Albino to Albino would produce, which assuming compatable strains of Albino, would produce all albino offspring.

Asking another genetics question.If I have a male and female that are both het for a trait all their babys would show the trait?
yeah well, for example X= albino (dominant), y=het recessive. Both ahve this Xy ok... Then that would equal XX, XX, Xy, yy. If im not mistaken that means 3 albinos and 1 of the hets...................................... if that does not answer his question i dont know what would...

Is their some kind of point for you arguing with me over this... any how he said, "Or if I have two albinos will all babys show trait," i interpreted that to be that he had 2 albinos het for a trait.

Are you saying that the Punnet square lies!? im just jokin with ya man, anyhow, i am right arent i? Or isnt Albino a dominant trait? Because if it isnt then 2 will definently be albino, 1 will definently be the het. and the other one will be 50/50.

It depends, albino is a simple recessive trait.
However, if we keep it simple and go w/ 2 Albinos then yes it is dominant and you will get all Albinos. In this case I believe it would be called a dominant recessive trait.
It is when you mix other recessive traits or dominant & co dominant traits that things get tricky.
Since the original question never actually stated any other trait, it would be impossible to determine if it was dominant or not.
Honestly, off the top of my head, I can't think of a proven dominant trait for leopard geckos.
However, as an example, hair color in mice is determined by a single gene with a series of alleles, each resulting in different coloration.
There are alleles for black, brown, agouti, gray, albino, and others. The twist here is that the same allele can be dominant or recessive depending on context. Allelic series are often written as agouti > black > albino.
This means that agouti is dominant to black, and black is dominant to albino. (And agouti is necessarily also dominant to albino.)If the black allele is in the presence of an agouti allele, the mouse will be agouti because black is recessive to agouti. If that same black allele is paired with an albino allele, the mouse will be black since black is dominant to albino.
