The Androgen Receptor is on the X chromosome and it is also this which is the predominant malefactor of MPB. For every X chromosome you have, you will have an additional and active AR gene. So to be rather blunt, if XX, you have that much more potential of having inherited MPB... and heaven help you if you were unfortunate enough to have inherited two affected AR genes from both your mother and father because it would be all the more aggressive and rapid.
It's not all bad though, that very gene dictates your entire androgen sensitivity and again to put it bluntly, that's the very reason why we require as much as half less than an XY male in our T dosage volume (and that, in turn, is exactly why not a one of us has any business attempting to adjust or else self-administer our own TRT; if you didn't know that, you'd find yourself in a heap of hurt eventually). Ironically, we're as much as twice more androgen sensitive (syn. efficient) than XY males.
On the other hand, the phenomenon of "recombination" (XX - the "long-arm" swapping; think a shuffling card deck, that is precisely what that is) itself opens you to susceptibility to have spontaneously acquired one or both AR genes affected, without any prior family history of MPB. So, it's fairly pointless to worry about this, really. If it happens, it happens. If it doesn't, it doesn't.
