Hi all, I'm new to this world and confused about all the abbreviations and some of the meanings regarding coloring.

I've looked up some of the words, but other abbreviations are confusing. For two examples, I saw somethings on other posts like:

Piebald, which I am familiar with from horses, meaning black and white, but the snake was not black and white

and

100% "Het", which I would have interpreted to mean "heterozygous" for the color trait, is that the percent chance that it is het? Or am I way off on what is being conveyed here?

If there's a good post already or a reference online for all these terms, I'd love to have a link to it.

Thanks so much!
Stephi
