Genetic question...possibly complicated

[melissa102787]

I have a basic understanding of beardie genetics. But I'm trying to dig a little deeper.

I have a Hypo Italian leatherback het. trans male. I was thinking about breeding him next year to two different beardies. I have a female leatherback who is double het (possibly) for trans and hypo/leatherback. That was what I was told when I bought her. I'm guessing SHE is not Italian leather back and carries the recessive leather back trait. Which is confusing because I have read some say leatherback is NOT recessive and are only co dominate. And then I have read there are two types of leatherback genes, recessive AND co dominate. I'm guessing the second is correct(please correct me if I am wrong).

I want to know what the probabilities of the offspring would be. Since there is hypo, leather, and trans genes. How many will be het, visual for each and so forth...Will there be a chance of normals? Also, since she is 66% possibly het for trans and hypo, could she be one and not the other??

And my second female is a citrus tiger trans. Since my male is hypo, leather back and het for trans.... what are the probabilities of the offspring?

Thanks so much!

Leatherback is not a recessive gene. They are either leatherback or not.
If your trying to prove out individual traits I would breed simpler so you can prove out your hets with no questions.
With all the traits you have tied up in the genetics I think you will have low numbers of everything.

How come there is so much different info on leatherbacks? There is this site, http://www.mbdragons.eu/en/genetica.html, that I have seen people refer too. It talks about two genes( I'm sure you have read it). Do you know any sites that have further explanation as far as genetics are concerned? Maybe more in depth reading?

I did breed out pair I had, and got a surprise last year. The male and female as far as I knew had nothing too special about them. Both I had bought from different friends that didn't know much about them. The babies came out mostly normal. BUT I had a couple exceptions. I had two babies with reduced scaling. They both had health problems though, one died the first week or so and the second only lived for two months.
It was her first time breeding... Not sure what happened with those babies though.
Both the male and female seem "normal". So I was a little surprised when I saw two babies look super smooth. I think I have a pic somewhere...

In the mbdragons link there is an article explaining the two types of leathers, codom and recessive. Also Josh from phantomdragons explained in fb or in diff forums the recessive trait in leathers, saying that is this recessive leather who combined with another recessive leads to the microscaled leather. But here i'm a little confused about this gene. Has anyone bred the supposed recessive leathers so to prove they are not actually recessive? Is it true about the microscaled leathers?
