Does my bp have any hidden genes or hets?

[jmcrook]

so she isn't a scaleless head..but she has the genes for it?

Nope. Scaleless head is the heterozygous form (single copy of the genetic mutation) of a fully scaleless (homozygous form) ball python. If it possessed this genetic trait it would manifest phenotypically as a ball python with a reduction of scalation on the top of the head.
