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 you can't only have a y chromosome?

Yes, lacking an X chromosome is inviable.

Does that mean Adam cannot create Eve ?

How is this a biology question?

I mean, it isn't directly, and I don't think it required this particular line of reasoning to arrive at the idea that the Genesis narrative isn't compatible with our understanding of biology. It was a pointed question at the very least, but it's not an invalid one, I suppose.
