Coral Glow / Banana genetics are confusing to say the least, but that does not change the fact that ball pythons use a ZZ/ZW system (in this system the ZZ are always male and the ZW are always female with the occasion parthenogenetic result of WW females ). This is knowledge is common throughout scientific literature.
