Her birth certificate is wrongly filled in if in reference to sex
I don't think so. She's basically all female except for some chromosomes. People get hung up on absolutes and 100% certainties with chromosome. Having an XY in the vast majority of cases indicates you will have a male but sometimes it doesn't. That would be this case.
Honestly, if we are going to be pedantic biological sex is a spectrum. Explaining that you only have XY for boys and XX for females is a simplification of the whole matter to help people understand the idea better. It's not wrong to state its a spectrum but its somewhat unnecessary when we don't use a spectrum for maleness and femaleness of people in the first place. It'd be absurd if when a form asks your sex its its like "ARE YOU A MALE? HOW MANY PENISES DO YOU HAVE? HOW MANY TESTES DO YOU HAVE?" because such exceedingly rare conditions do exist where men have two penises and men have more than two testes (or less).
That's why i personally feel its just better to stick to male/female/intersex rather then trying to make this claim that its a spectrum. Its technically correct but completely unnecessary.
Not really though. A spectrum indicates a range of sorts when in reality there's male, female, and then several mutations that occur from time to time, most of which still fall under either distinctly male or female. Basically, there's male, female, and then a bunch of radical outliers.
Your point being? Those people still exist and still have to fill out forms that ask them whether they're male or female and said people don't clearly fit into either male or female but you can make an approximation of one over the other. There also people with things like ambiguous genitalia. Just because something is rare doesn't invalidate its existence lol. However, its rarity is precisely why i feel we don't really need to call it a spectrum and can just stick with 3 discrete points. A, B or AB.
Exactly... that was my point. A spectrum indicates some fluid range of possibilities. A few mutations doesn't a spectrum make
