He could… But he does not want to and you cannot make him
During the final stages of follicle building and moving into ovulation, the females experience a hormone rush. These hormones cause an imbalance in the normal balance of pigmentation expression which results in the females overall colour-tone changing
Here you go @halohelix! The first picture is of my Mojave Vanilla Sulfur glowing and the second is how she normally looks. Not all ball pythons have such a dramatic difference, it can be harder to tell in some combos, but it’s really noticeable on this girl.
Interesting thing there… In most species, the hormone flush leads to hypermelanization, like we see in @osbornereptiles’ GTP. But for reasons that I do not have been looked into, in balls it seems to lead to a hypomelinization
In GTP it happens as hypoxanthism. All of the yellow pigment is flushed out and high yellow adults typically turn very “white” where yellow is released. Some animals have remained as hypoxanthic but most return to normal almost immediately after eggs hatch even when artificially incubated.
It’s funny you say that because when I bought her, she was marketed as possible Vanilla. This will be her second clutch. I am hoping to prove she is or isn’t. The last clutch had one snake that I thought could have been Vanilla Ghost Pied, but because there was just such a small sample size and 4 were Pied Ghost, I couldn’t confirm it. This year she has been paired with a Vanilla dbl het male so I am hoping to hit just one super which would confirm it for me. Here is a pic of the whole clutch and the boy in question which I have posted before
Honestly if you don’t know for sure it’s better to sell it as possible. And worlds first honestly doesn’t really add to a snakes value unless it’s some new gene.
I didn’t advertise as possible because the mother is an unproven possible. I’d rather under promise and over deliver than vice versa. As for the first, it would have just been for bragging rights. Let’s face it, being just a hobby breeder, it’s not likely to do anything first these days.
