You're comparing genetics of one species to crossing two entirely different species? I'm sorry, show me the "same thing" about that. Hybrids often cause detrimental effects on different species much worse than any genetic deformities associated with morphs.
You keep bringing up that hybrids are naturally occurring, and in some species they are, but we're talking about a very specific hybrid here. Naturally occurring ball python x Burmese python hybrid? Good luck.
How does something like that happen by mistake?
"Oh hey guys! Let us put this ball python and Burmese python together and SEE WHAT HAPPENS!"
I think they're lying out their arse.
