How common is this? Any of these? 1 in 5? 1 in 20? 1 in 100? I asked because I’ve had a long week at work and I’m just mentally tired but curious. Ok, I googled.
Kleinfelter syndrome. 1/650-ish.
Turner syndrome. 1/2000-4000-ish
Ambiguous genitalia. 1/4500-ish.
(Actually, so far, more common than I expected to be honest)
A human Chimera? 100 documented cases. I think there’s something like 8 billion people on the planet right now for perspective.
What is the frequency of humans born with red hair? 1/50-100-ish.
What is the frequency of Down syndrome in humans? 1/700-ish?
What is the frequency of polydactylism in humans? 1/500-1000-ish (usually only on one hand also, but whatever, & I’ve met a guy with three thumbs). This is much more common in humans than some of these other syndromes. Does this mean that humans (generally, I guess) don’t have 8 fingers & 2 thumbs?
What are the odds of a human being born a red-headed polydactyl Down syndrome? I’ve no idea.
What does that mean? I have no idea.
