Xtreme gene question

For those of you worth xtreme gene combos what are you looking for when deciding the xtreme gene is in that animal. I know you can see striping formally and on the single gene I see quite a bit of yellowing on the sides coming up from the belly. An help would be greatly appreciated.

A quality Xtreme gene is unmistakable. If you want to see great examples then you have to check out @ssscales on IG. I have some from him and they are unbelievable...

Thanks
