Beardie genetic morphology?

[dinogrrl]

I am wondering if anybody can tell me whether there is a site, or any recommended book I can read that can tell me more about Pogona vitticeps genetic colour morphology. I have read many sites that discuss basic mendelian genetics as pertaining to snake and leopard gecko morph breeds, but I am unsure if these pertain to a bearded dragon. Is it the same for beardies. It seems too simple. How many alleles are involved in beardie colouration? I just find it hard to believe it is this simple, and I am certainly interested in knowing all I can.

I have a normal phase beardie, that shows incredible yellow colouration, does this mean she is actually normal phase? How are colour phases determined and created - just by visual phenotype assessment?

Hope some well informed enthusiasts can clarify this for me, I'm so confused!

Thanks in advance!
