Which chromosomes do you have?

Two X's.
Hate it.
Can't do much about it.

XY aka Male and I have never taken a biology gcse.

I went to a pub where the doors for the toilets were marked XY and XX. I think Mark Watson was talking about the same pub the other week on TV. "I didn't know you needed to have a biology gcse to use the toilet!"

Seriously though how many people don't know that two X chromosomes means female?

Loads of people, I'd imagine.

I used to think everyone knew the song Snoopy V. The Red Baron. APPARENTLY NOT!

Out of interest, why isn't there an option for "other" to include people with Klinefelter's, Turner's or other rare syndromes (ie XXY, XO etc)

I don't like 'other' options. As for Klinefelter's, Turner's or other rare syndromes, this is simply 'Are you a boy or girl?' disguised in fancy biology wording. If I just had just asked 'boy or girl?' I wouldn't have included an option for transsexuals, or any other gender deformity for that poll either.

Stop making me laugh so hard I spurt water out of my nose.

And anyway, XY.

...the heck? XD
We need to start an intervention for Paul. No more weird polls.

Honestly...I don't know, and don't really care. XD

...Er, XX = female chromosones, XY = male chromosomes. Which I always thought was common knowledge, but there you go.

XD You can tell I don't like Science.
In that case, XX.

That's because you're pretentious and superior. My dad didn't know!

How do people not know, though? I just don't understaaaand. D:

(And I'm not sure you should be saying anything about people being pretentious and superior... ;P)

'cause they were never told, I suppose. Hell, how come you know? Someone told you.

My Dad went to school in the 50s and early 60s, and then did History at University and just..never came across it, I guess?

And younger people probably didn't pay attention in Biology class.
I know I didn't.

People with chromosomal mutations that put them in the "other" category are often severely mentally disabled and probably would not be posting here anyway. (That's what it said in my textbook last year, anyway, so don't jump on me if that's inaccurate.)

I think that's only XYY Syndrome. The rest are associated with developmental delays, but the spectrum is very wide, and generally they're in the same range as most non-chromosomal-abnormality people.

Actually, XYY syndrome causes, for the slight majority of cases, no discernable side effects. You just get a guy who's a little taller than his tallest parent, and may have slightly more body hair than otherwise he should.

XYY males may have learning or language disorders at a markedly higher rate than the population (a little under 50%, compared to 10% for genetically normal folks). IQ scores are slightly lower than that of siblings, but that's normal - there's usually that sort of variation in chromosomally-normal families anyway.

What I've been wondering is this. Everyone has at least one X chromosome, because a female is only capable of providing an X. But what if, hypothetically, never mind that this can't happen, what if someone were born with two Y chromosomes? Do we actually have any proof that an X is needed to live, or is it just assumed because it's impossible to have a baby with two Ys? Who knows for sure if a YY kid would grow up just like most regular, healthy people with XY or XX? That's what I want to know. I really do.

Well, a YY would be impossible as a female MUST give an X chromosome.
I think that a person with a karotype of YY would not be able to live as when the featus is forming, every person starts off as a female before either progressing to become a male or remaining a female. That is the reason men have nipples. So if there was no X chromosome, this first stage could not occur and the featus would not form properly.

That's just my theory though.
