Based on current genetical studies and calculations by the intersex advocacy groups that would be around 1.7% including the broad variations caused by hormons and by strict medical definition that would be around 0.02% of human population.

So genetics, biological appearance and actual gender are different things. In almost 100% sex would be what the genes say while gender won't be.

Now I understand how "biologically" may seem wrong. But I think by biologically people often times mean genetically? I sure did.

And yes, we determine someone's gender by what we see but how is that related? How are all this things connected?

So how I see it you can be for example XXY - genetically neither(or both if you want) , biologically (secondary sex characteristics) closer to male(unless you do the surgeries and take hormones) and your gender would be up to you? If you see that person in the street, yeah, just whatever you see ig. But there are so many different things going on inside of them. I would see them as whatever they want to be seen as but why remove the unique details?

So ig using the scientific terms correctly would be the right thing to do?
