Pretty sure according to current science, the sex is “undifferentiated” until a certain point in development. That means Trump wrote it so no one is female, lol.
As the article points out until the genitalia develops it’s impossible to accurately predict the sex of a fetus due to instances of fetuses with XY chromosomes occasionally developing as female. On the other hand it should be impossible for an XX fetus to develop as male as far as I know.
It’s rare but possible. Basically, the piece of the Y chromosome that hosts the SRY gene can wind up swapped onto a different chromosome and still work its magic. You really only need that one single gene to trigger the whole cascade of development that makes a person male.
I think another interpretation of Trump’s order is that nobody is female, since no embryos are capable of producing the “large reproductive cell” at conception. At conception they’re just a single cell, they aren’t producing any reproductive cells yet. That’s not until quite a while later in development.
Fair. But if we do include intersex people with less common chromosomes in this topic, I wonder if they might get overlooked? I hope so, since it’s probably the best chance here except in the unlikely case a “wait and see” stance is allowed.
*edit - correction: I somehow forgot that as orclev said (and usernamesAreTricky expanded on with a vice versa), it’s possible for XY folks to be cis women. So chromosomes don’t deliver the desired gotcha either.
Expression is where it’s codified. For instance: I have XX chromosomes, but I also have dangling genitalia and a great big bushy beard. All because the X chromosome I recieved from my father had an SRY transcription error, and my body had male expression “switched on” by the SRY gene.
Thanks for pointing that out. When I first checked the link, I must have been tired as I missed that there was an article beyond the image and headline somehow. (Normally my habit would have been to check if the topic was covered, since headlines can be misleading. Case in point, in this case they were going for humour more than accuracy there, but the article indeed has examples.)

Even as a zygote, the chromosomes are still XX and XY, aren’t they? (Ignoring XXY, etc.)
It’s still stupid as hell, and the female thing would be funny-sad, but scientifically I’m not sure it’s accurate.
not all people with XY chromosomes end up with a penis.
not all people with XX chromosomes end up with a vagina

Yep
It rather depends on how you’re defining sex. And I’m not joking, the article gives good examples on when it is ambiguous.

This is 100% understandable… Especially on a phone these days it’s getting crazy hard to read articles.
