The color phases of beardies are a product of selective breeding like what Jeff Ronne has done with his "pastel" line. They are not co-dominate merely an inherited trait. Much like blonde hair and blue eyes. This is proved by the variances in each clutch. A codominate trait would produce a number close to 50% looking like the parent with the desired trait..... This is not true in any of the color phases of any of the bloodlines. There have been different color phases bred for out of the same bloodlines. Sandfire yellow, sandfire red, and sandfire orange is a good example as all of these color phases were produced form the same bloodlines. Selectively breeding the yellow ones to the yellow ones has started producing some super nice yellow sandfires but you can still get reds' yellows, oranges and normal colored animals from each clutch. The genetics that create these color phases can pop up seven generations later.... A polygenic trait. I believe this info to be true because I bred a Redflame/sandfire red feamle to a Zilla/sandfire yellow/pastel male and in the clutch of 13 I had a couple that looked pastelish, one that resembled a sandfire red/flame, two or three that looked sandfire yellow, so on and so on....



As for recessive traits..... There are a few of those starting to emerge in bearded dragons. Hypo-pastel and marketed leusistic are actually one trait. Hpoymelanism. This was proved by Rob and Vicki Dachiu as they bred a Marketed Leusistic to a Hypo-Pastel and got 100% clear nailed offspring. So there are two seperate bloodlines of hypomelanism out there.



Another recessive trait is hypo-irrisistic or "translucent". These dragons lack the ability to reflect the base color of white due to misalligned platelets or "irridiphores" causing them to have a transparent look.



Though albinos aren't in the USA.... (supposedly).... They have been produced in Australia.... Another recessive trait as well.



If you have any other questions please email me.... phone chats are better for this as I could type till I'm blue in the fingers....LOL
