Several years into proving out a potential new gene "AB", input appreciated!

[AB]

I have been working on this project for quite a few years, unfortunatelly I don't think I'm much closer to an answer as I was in the start. I am presenting what I have so far, all ideas and feedback are well appreciated!Back in 2014 I pasted a comparison of our "strange" normal female, which we bought from an Italian breeder in a package deal several years prior as a regular normal ball python. Back then I compared her to a Cinnamon, just to show how dark she really is. Please find pictures below.Here is the girl in question.Here she is being compared to a Cinnamon.3 years later, here is a most recent comparison. Original female is on the left. On the top is her son from the first clutch she had with us, back in 2014 - father of that clutch was a regular Enchi Lesser, none of the babies in that clutch looked like their mother, so I only kept one, this boy. Pattern on her son looks similar to a regular Enchi Lesser, however in reality he is very dark for an Enchi Lesser (he shedded 2 days prior to taking this picture, so he is as bright as he can be). Pythons on the bottom and right were hatched lin 2016 by breeding original female on the left to her son on the top (she hasn't been bred to any other males in years). Unfortunatelly there were only 2 viable eggs. What are these two pythons on bottom and right? Your guess is as good as mine. Pattern on the right one looks similar to a Lesser, but the color is totally off, in reality it's almost golden/green, Python on the bottom has a very similar pattern to his mother, but the color is totally different - reminds me of Mojave.I guess only time will tell what is going on here, if anything at all, but for now your input is well appreciated!Thank you for your time and Kind regards,Andrej
