Does my bp have any hidden genes or hets?

a yt video it says if her last scale before the vent is split then they're a scaleless head, and she has that.

It would appear you have taken something they said a bit out of context. A scaleless head still has noticeable difference in the scales on the head. What you are describing is another marker in addition to that.

Yours has an interesting pattern that is atypical for a normal. It may or may not be a morph. No way to know if it is heritable without test breeding. Many normals can have oddities to their pattern or colors without it being something that passes on to offspring. There are a few at the top of my head that it could be, but without knowing the lineage of the animal or having something more obvious, it's safe to assume it's a normal.

With very few exceptions, what people refer to as "hets" are not something you can tell by looking at the animal. When someone says an animal is het something, they mean it carries that morph, but two copies are required to give a visual effect.
