Super Coral Glow - male or female maker?
I tried searching and it's purely a curiosity, with sex being linked has anyone figured out what this does in a super form in regards to the hatchlings being male vs female makers?

I would guess it'd be towards a 50/50 clutch, but I'm not positive

Not with ball pythons you can't.
As for CG and Banana they are the only known mutation affecting sex ratio, why? No one knows it just does.
Males produced by a male CG or Banana will produce males Banana or CG and very rarely will produce a female CG or Banana
Males produced by a female CG or Banana will produce females Banana or CG and very rarely will produce a male CG or Banana
Females will produce equal sex ratio.

The best way I can describe it on the more genetic level. Is that the gene for the banana color allele is found on the sex chromosomes. On a female it doesn't do the sex ratio thing since there are 2 X chromosomes and it doesn't matter which chromosome the gene is on. It works with males since there is only one of each. And if the male banana gets its gene from its mother, then the gene for banana is on its X chromosome. So any time the male sends an X chromosome making a female baby, it'll carry the banana gene with it. Where as sending a Y chromosome won't have the gene. Making a female maker. the same is true for the male side of the equation.
The reason for the random male or female banana where it shouldn't be, is due to crossover. Where during mitosis or meiosis, genes get swapped from one chromosome to another, swapping the banana gene from the X to the Y chromosome in a female maker, giving you that random male. The super form of the banana has a gene for the banana allele of both the X and Y chromosome, so all male and female with show as banana.
I hope this makes sense. And helps some.

The problem with this is that the female is the heterozygote (ZW) and the male is the homozygote (WW).

That does throw a kink in that train of thought. I was working off the assumption they had a chromosomal structure similar to mammals. I need to do some more looking into reptile genetics. I wonder how works then?

Has this been proven or is it still just assume from other snakes? Because if females were heretozygotes then wouldn't partho clutches be equal ratios instead of being all female?
