Some XX people live their entire lives as men without ever knowing otherwise, and the same happens with XY individuals living as women. Even having children won't reveal the apparent discrepancy, unless they need certain tests done.

This is the best resource I've seen to show things relatively simply.

The TL;DR is that a whole "Y" chromosome isn't exactly responsible for "maleness", the SRY gene is. It's normally on the Y chromosome, but mutations can occur placing that gene onto the X chromosome. Inversely, someone could inherit a Y chromosome without that gene, in which case they would develop with female traits.

It's not considered trans because someone with 46XX plus the SRY gene would develop male genitalia, be identified as male at birth, and likely identify themselves as male. For some types of these conditions, there are plenty of people walking around with no clue that their chromosomes don't match their gender.

Disclaimer: I'm not a geneticist, so i could have explained something a little off.

I googled it for you.

https://en.wikipedia.org/wiki/XX_male_syndrome

In 90 percent of these individuals, the syndrome is caused by the Y chromosome's SRY gene, which triggers male reproductive development, being atypically included in the crossing over of genetic information that takes place between the pseudoautosomal regions of the X and Y chromosomes during meiosis in the father.[2][7] When the X with the SRY gene combines with a normal X from the mother during fertilization, the result is an XX genetic male. Less common are SRY-negative individuals, those who are genetically females, which can be caused by a mutation in an autosomal or X chromosomal gene.[2] The masculinization of XX males is variable.

Error: url1 and url2 are the same

True, but I do think it was warranted in this case.

This is putting confirmation bias to the extreme.

Well you don't know people with PhD that don't tell you they have one

My take is that sex-linked characteristic are grouped together due to prehistoric and historic evolution. Since I dont have a womb my tits would not have been worth the energy cost in an ancestral environment. Therefore, they are not coded in my DNA and I have to dose to maintain them.

There are people who are different, that is a fact.

Some folks are given "PhD", others are kidnapped and sent to concentration camps. Is the education system legitimate, or corrupted by authority?
