Can someone explain the meme? I’m a little slow.
But not really. They still have the Y chromosome, but the genitalia is kinda female before it fully forms
Wrong mate. Check out Swyer syndrome.
XY vs XX chromosome is meaningless, since XY females occur in nature.
We all start as female and testosterone turns half of us into men.
Edit: I also just learned that XX men exist. It’s called De La Chapelle syndrome. TIL.
It’s not just X and Y chromosomes that determine sex though, from what I’ve heard (from actual biologists). I don’t know the specifics though. I wish we could have up-to-date biology facts like this taught with the basics in grade schools, but I can only imagine the uproar while hostile parents are still going to court over effing gender pronouns.
Incorrect. Without intervention by hormone signals, literally every human fetus would develop as a “female” with all the traditional female sex organs and morphology. I believe they’d even be capable of generating eggs and carrying babies, but I’m not as confident on that.
A lot of people think that the XX or XY is determinative or definitional, but it’s always the hormones, baby.
Human embryos (and probably others) start out female, and grow the male parts a fee weeks later. There is probably someone lurking who can give better details but that’s the gist of it. Thats why men have nipples.
Yeah the Y chromosome doesn’t kick in until later in fetal development.
There’s actually a surprisingly small amount of biological information stored on the Y chromosome, IIRC the vast majority lies on the X.
You pretty much nailed it.
Also, it gets much more complicated than that; at least 2% of humans are intersex, meaning they’re a mix of male and female, everywhere from outward presentation (rare) to chromosomal (more common).
It’s not just gender that’s a spectrum: sex is, too. I said ‘at least’ because it’s possible for people to go their whole lives without realising they’re intersex. 2% is huge: if you know 100 people, statistically 2 of them are intersex. Most of us know more than that.
The ‘only two genders’ thing is biologically bullshit. Biology is never cut and dried.
eta: for reference, I have a disorder that’s been in the spotlight lately – Ehlers-Danlos – and you’ve probably at least heard of it. You’ve likely talked to someone who has it recently. It occurs in 1 in 20,000 people. Again, roughly 1 in 50 have intersex traits. I wish this had the visibility it deserves. It’s exceedingly normal.
The He-Man series back in the 80s always ended with little moral quips, so this is mimicking that.
The fact is that all fetuses start off assuming female, and then the presence of certain chromosomes trigger male anatomy.
Hence all males being trans if life starts at conception, as at X week development shifts to generate the male oriented organs.
At least that’s my understanding of this meme…
presence of certain chromosomes
well, the presence of certain hormones that are usually regulated by some genes on certain chromosomes
And the reception of those hormones, which may not exist or may not be functional for some people.
Turns out making beings out of trillions of cells of 100s of types (all of which have basically the same 3 or 6 billion base pair genome, yet have to act very differently) is complicated and any process has many steps, which involve various genes, receptors, signals, etc, all of which could be interrupted.
Cis and trans are mutually exclusive
Edit: why am I getting piled on for this? Cis and trans are literally defined as opposites.
Only if you’re trying to say they didn’t have a gender identity yet as fetuses. That’s why it’s a meme and obviously a joke. Otherwise it makes an interesting point about how silly it is for cis people to base gender on body parts.
correction: 8 days later, I am editing to state I have since learned biological sex is actually undifferentiated in the first weeks of a pregnancy. This is NOT the same as being intersex, but I think an intersex individual would probably have the best perspective to weigh in on whether the joke in the meme still makes sense, due to overlap in the issues it raises. To my knowledge, I am not intersex, so I’ll shut up now.
Trans is about how your gender identity relates to their assigned gender. If life begins at conception and you assigned gender at that point, everyone should be assigned female. Anyone who identifies as a man would have a gender that doesn’t match their assigned gender and therefore would be trans.
