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.
Close up, in focus pictures of the top of its head would be helpful in identifying. If you didn’t buy it as a scaleless head then it’s highly unlikely that it is.
