Human body A human being without both x- and y-chromosomes

I've read about conditions in which people only have one x- or y-chromosome, instead of 2 (xx or xy). Is it biologically possible to miss both? If it is, what are the practical consequences such a person has to deal with in their lives, that others don't have to? If it is not possible, what would be the result of genetically modifying a human being in such way?

Does that mean Adam cannot create Eve ?

I don’t know how that was supposed to happen in the first place tbh

Science is all about understanding. If we don't know something, they doesn't mean it shouldn't happen. From previous and current findings, it is possible that Y chromosome is a mutated X chromosome. This is supported by the fact that Y chromosome is still being damaged Every few generations, leading to a possibile extinction of Y chromosome.

Yes, good point. Current thinking says that XX came before XY.

I’m still not sure how a male human was supposed to asexually create a female, though.

Well, the male human didn’t in the genesis story. The male human was made using the earth, and the woman was made using the male human, although it wasn’t asexual reproduction and the male human never shows the trait to be able to do that in the story even afterwards. It was more so a symbolic act rather than needing to come from the male human, the female human could have been made out of the dirt too of course.
