Palmetto genetics

I'm so confused. I read on one site that this dominant, then on another it is recessive? I read that it is either they visually show the gene but can be either a het or homogeneous but still visually show it, then one another site I read it can be het but not always show visually. :shrugs:

What is it really? Dominant, incomplete dominant or recessive?

Can they be het and not visually show the gene?

Would really like a genetics nerd to clear this up for me. lol k_01:

It's currently considered incomplete dominant. You still need two copies of the gene (homozygous) for the snake to look Palmetto. Having a single copy of the gene (heterozygous) creates a somewhat hypo-like appearance. Does that clear it up?
