She was sold as normal. The pattern to me is either terrazzo or Aztec I think? But never thought she could be a cross i hope not.
I don't see any reason to think that she is a cross.
Her pattern is "Aztec".
There are plenty of Corns with the Aztec pattern.
As Susan mentions, it is rather common with Lavenders. However, Classics, and other morphs, (without Lavender influence) can have Aztec patterning as well.
It looks like your girl could be Hypo. Although, with her looks, it is also possible that she could have other influences instead.
There are Classics/Normals (with orange belly checks, &/or reduced black, etc.), out there, that can look Hypo but are not Hypo.
If you truly want to know, test breeding would be your best option.
BTW She is a pretty girl.
