Notwithstanding errors in gametogenesis, every ovum has exactly one X chromosome and every sperm has exactly one X or one Y chromosome. The resulting zygote has two sex chromosomes, either XX or XY, except in the case when there are errors in gametogenesis (note that this kind of error is abnormal and the result of some failure in the process of meiosis). Even when there are -- abnormally -- three sex chromosomes, in order to have a viable organism, epigenetic processes necessarily silence the genes on one of them so that the correct dosing can occur for expression and subsequent translation. In summary, the cellular machinery in humans (and really almost all eukaryotes) is fundamentally organized around binary sex chromosomes. Sure, in a very small percentage, failures in the usual processes can still result in a viable organism, but these are failures and not normal biology. Certainly I wish intersex individuals healthy and fulfilling lives, but the biology that resulted in their chromosomal makeup is not normal.

And, frankly, using intersex and infertile individuals to advance your evil agenda is really despicable.
