Any “transwoman” is genetically lesser compared to a real woman, aside from the overt Y issue, as I had suspected for some time. After which point, the book discusses genetic diseases of the chromosome (they often shamelessly use these people as a verbal fucktoy and shield “what about people with different chromosomes?” as if it isn’t a disease).
I wasn’t insulting men either, the common speculation for this difference is that women need a full suite of genetic material to potentially pass on to and/or bear children.

I should probably quit while I’m ahead, I’ve spent far too long mulling this over with a geneticist/biologist and things are getting fuzzy. All this talk of allosomes and mitochondrial DNA (mtDNA).
