The GeneX Ball Python was first discovered by Justin Kobylka around 2015.

"GeneX started with a captive-hatched animal. An amazing, very odd girl with melted sides and unique belly striping that is closer to center of the belly than typical belly striping.

The original GeneX female was put directly into my Pied project the first year and reproduced her look in her first offspring. The following season her linage produced the world’s first Yellowbelly Pied (aka Pumpkin Pied) here at JKR way back in 2008.

I didn’t think much of this unique gene until others also began producing YB Pieds that were not as bright as my original. That is when I started to consider that this unnamed gene was having a significant influence.

In order to give it a label for tracking it in my own collection I called these animals GeneX. I never intended that the name would stick!

In the past couple seasons I’ve been able to identify the gene more reliably as I’ve gone through nearly 4 generations. 2015 was the first season I was able to focus on what combos it could make." - Justin Kobylka [2]
