Ha, I tried understanding double hets in The Complete Ball Python book by Kevin McCurley and I got more confused - mainly because in his example the caramel albino was designated with ccGG and the Ghost was designated with CCgg (I guess I was thinking that the capital letters should be opposite). My head started spinning so I put it down to try another day! LOL
Really need to understand it too, because I think a hypo clown would be awesome!
