Hi Jen,
I can't really explain co-dom traits using leopard geckos as an example...
I would suggest going to a ball python website, or the ball python forum and look for pics of Pastel Jungle ball pythons (Co-Dom trait het for Super pastel), and super pastel pics.
Basically with the pastel trait (het) you will see something in between wildtype and the "super" trait (homo).
A pastel ball python has more yellow and blushing than a normal, but a super pastel has extreme amounts of vibrant yellow and blushing.
The big difference between co-dom traits and simple recessive traits is that co-doms phenotypically show the het form of a trait, while simple recessive hets will look like wildtype.
As far as comparing co-dom to polygenic traits... like carrot tail. The main difference is that co-dom traits are controlled by one single loci, while polygenic traits are controlled by many different genes.
You can have hets for co-dom, no hets for polygenic.
Hopefully this helped some, if you have any other questions let me know.
