to point out that one Y chromosome does not make you a male

[Nimbostratus100]

In response to other posts insisting that one genetic test and one Y chromosome makes an athlete indisputably male with no room for error, I just want to point out that it not true.

There is always genetic exchange, for example, between a mother and baby, so anyone who has had a son will still have Y chromosomes in some cells in their body, and that will possibly show up in a genetic screening.

I am all for keeping men out of women's sport, and defining them genetically, but please lets not go over the top - one test does not prove you are male

🤣🤣🤣🤣

Very true.

I'm swimming there is at least 2 people who watch you do your urine sample.

Come on Nimbostratus! Show us your sciency evidence!

Honestly I don't think there is a lot of ignorance around this. It's not new knowledge. As your outdated research papers quoted indicate. Why are you selling this as a new thing. Testing already takes this into account. I would have hoped anyone with a bsc in any science would be aware of this and anyone with an interest in trans issues.

What "cause" is this you speak of?

Have you seen this video footage? I suggest you watch the entire video.

Unsurprisingly, you are correct, It doesn’t!

Category eligibility is decided on more than one test and ultimate decisions are in the hands of The Court of Arbitration for Sport in Switzerland (who also rule on stuff like length of running blades for para athletes)

OP seems to be trying to create outrage at all the stupid mean mummies who know what a man is and want fairness for female athletes (and most us are well aware that it’s not always a simple answer when it comes to athletes with a DSD, who are a completely different category to standard XY males who gender transition).

This is part of the problem, very simplified patterns taught at GCSE level, which is fine, as it give a good foundation to build on, but does not always represent the full reality, and people who don't take a subject any further are stuck with the GCSE over simplifications in their head for life- genetics isn't the only topic that this can be an issue in

And anyone with an interest in Women’s Sport!

it is happening, that is why I am trying to explain the science to people a bit more. It has happened to a friend of mine, and it is very distressing

What's the story here?

so you will most likely have Y chromosomes in cells in multiple parts of your body, but you are still female, and have no male advantage in sport. That is the whole point

However, if you are tested, you might show up as male, there is that chance. In which case, you would need to be tested again

The friend goes to a different school, and none of us know her.

it is happening, hence the thread

Yes, what exactly happened? How many stupid women that don't understand genetics were involved? What did they say to your friend? What elit sport does your friend do?

so you will most likely have Y chromosomes in cells in multiple parts of your body, but you are still female, and have no male advantage in sport. That is the whole point

Yes - and humans will often contain cat DNA in various places, and may test positive for being a cat.

Maybe they don't specifically teach you this in GCSE biology, but that's not a failure of GCSE biology...

Well, luckily, a GCSE in biology isn’t enough to gain employment in Elite Sports Science testing.

Surely you know this? 🤣

As you say it is the solid "good foundation" from which to build knowledge and understanding. As a biologist myself, as any good scientist would agree, you start with first principles and build from there. If as you state you are a "geneticist" then you already know that you are spouting pseudoscience.

Fortunately though, microchimerism is both micro and primarily occurs in those who have given birth. This is a small minority of women athletes and even more importantly will mean that the athlete in question is demonstrably has a womb...
All guidelines have edge cases, that's ok so long as the number is minimal and there's a way to follow up and make a call - both of which is true here.

What is happening/has happened that caused you, as the OP of this thread, to need to start this thread to tell us that people are being declared male on the basis of one Y chromosome being found?

So as a 'geneticist' apparently, are you saying there is no reliable test to determine whether someone with female appearing genitalia actually has XY chromosomes? Because if that's the case it's important information and contrary to what I understood.

Or are you saying the tests are complicated and may need to be replicated to ensure reliability? Because that's not a revelation frankly, and your assumption that a) the general public would have access to early results and b) therefore get the pitchforks out for these athletes is...a stretch

@Nimbostratus100 but what I am pointing out is that the reflex hate, hostility and aggression from people supposedly wanting to support women's rights, does not help in any way, and there needs to be far more understanding towards women who are found to have a Y chromosome show up in their testing

Only 1 side is hateful, hostile and aggressive. Look in the mirror mate.

So then you present yourself to a doctor with your birth certificate 🤔

(And by the way, in elite sports, it happens quite frequently that people need to be tested more than once - athletes produce an A and B sample as a matter of course after races and samples are rerequested if there is any potential for contamination or difficulties with the sample taken. The fact of retesting really wouldn't suggest anything genetic, unless someone made a big circus around it).

so, mocking the fact that I am severely dyslexic, and typing one handed in bed after major surgery makes you feel good, does it? And why are you doing that exactly? Because I am pointing out that aggression and hostility is being directed at people who have done absolutly nothing wrong, and you respond to that with mockery.......

I dont care, I dont know why you think I would

I would not like to be that sort of person myself, though

No geneticist would actually believe that this mother of 4 sons would show up, in any test, as a male 😂🤣

because I have witnessed it, including this week
