I would suggest from a self diagnosis perspective that if a person had a balance between these 2 chromosomes in whatever strange pattern would bring forth a human snake/reptilian disability then the male half is not the insecure or unstable one, he is still not immune to emotional abuse but is able to take it way lighter like being teased barely bothers him, the female side however would react very poorly to emotional and sexual abuse creating a huge psychosis and large amounts of unforgiveable ptsd. The male side is the whore the female side is not /shrug.
(this is not trolling, but rather just speculation)
If in this universe it would be physically possible to actually build an impenetrable defense shield like pic related, how could it possibly be done?
My guess is that it may be possible to emitting some kind of pattern of some kind of field(s), in such a way that at the desired shield boundary the waves intersect causing a constructive interference, in some way that interacts with the gravitational field at the shield boundary, which we know from general relativity bends light, allowing it to stop any kind of radiation, or cause any kind of matter to disintegrate.
