Two X chromosomes.
It doesn't matter if she is surgically altered to look like a man (complete with urinary appendage), she is still female ... pretending to be a man.
By the same token, a single Y chromosome makes the person male, and all the surgury and hormone replacement therapy does not change that simple fact.
It's like owning an Apple computer, running Windows on it, and pretending that it's a PC.
In any case, genetics is the determining factor.
please catch up with what we now know. a person can be XX and have a male brain.
A male can also have two X chromosomes, one of those X chromosomes having the SRY gene that causes him to develop a penis and testicles in utero. (Although he might need testosterone during puberty to develop male secondary sex characteristics like facial hair).
Women can have one X and one Y chromosome and female genitals -- in Swyer Syndrom and Androgen Insensitivity Syndrome. (They, too, would need estrogen at puberty.)
People can also have mosaicism or chimerism in their sex chromosomes -- meaning some cells in their body have the XX karyotype, while others have the XY karyotype (they may have more than two karyotypes, too -- includeing XO, or XXY). Their bodies may develop to have mostly female sex characteristics, mostly male sex characteristics, or more ambiguous sex characteristics.
Even experts in fields like endocrinology (probably not all of them, but definitely some of them -- I don't know about numbers/ratios) conceptualize biological sex (whether or not you include the brain and gender identity as part of that) as a complex and fragmented thing rather than something black and white. You can't say that any one sexually dimorphic physical structure absolutely determines the sex of the whole person/whole body, because each sexually dimorphic part of a person's body can be feminized or masculinized separate from the other sexually dimorphic structures (including chromosomes, in a way -- because of things like: Translocation of genetic material like SRY that results in XX males; Alterations in the functioning of specific genes like the androgen receptor gene that results in AIS, or nonfunctional SRY gene that results in Swyer Syndrome; XX/XY mosaicism and chimerism; and who knows what else that I'm not aware of or that nobody is aware of yet that may be discovered in the future).
