Pastel- Co-dom, recessive...?
I was wondering if the pastel coloring is a result of a recessive or co-dominant gene in RTBs ? If it is co-dom, is there a "super" form? I am asking because I met someone who wishes to breed an adult male pastel RTB to a normal as well as another pastel. We are unsure of what traits the offspring will have.
Re: Pastel- Co-dom, recessive...?
From what I have read, Pastel is recessive, but not simple recessive. Therefore it will show up in some babies if no other dark gene is overshadowing it. Pastels are often brought in to 'cleanup' the look of a certain line of already light-ish boas. But you will not see any boas 'het' for it. I would say it behaves like a co-dom, but I have yet to see a super form. I just have one male pastel right now, would love to get him a nice clean looking female pastel.
Re: Pastel- Co-dom, recessive...?
Pastel is neither a recessive trait or a co-dom trait. It is polygenic. They generally produced via selective breeding alone with other morphs (salmon, arab, jungle, etc) to help "clean" them up.

Okay, thanks for the input. I guess pastel is a tricky trait.
Mezclado_Reps - what will be the offspring from the pastel pair?
Re: Pastel- Co-dom, recessive...?
From what I understand basically all the offspring would be pastels, but to varying degrees. The better the parents the better the offspring.

It was Jeff Ronne that dubbed the trait "pastel" quite a few years ago, and at first he believed it to be a recessive trait. After successive generations of selective breeding continued to become lighter and lighter, he concluded that it was in fact (as stated earlier) polygenic, and could be further refined with more selective breeding. The pastel trait itself doesn't make the beautiful pinks and oranges seen in some lines, but it reduces the darker pigments throughout the animal. This allows the colors to come through that much more.

Very nicely done!
Pastel trait is exactly that, but it's even better when added to a colorful gene pool, hence...

Are you looking to place one of your herps - I'm looking to own again.

Looking to adopt Burm, rock or retic.
