What we found
Our results showed that among identical twins, if one was trans, the likelihood that the other was also trans was 21.2%.
For non-identical twins, this rate was significantly lower, at 8.7% – though this was still well above the 1–2% prevalence of trans identities in the general population.
Non-twin siblings weren’t included in our research, but we’d expect their rate would be similar to that seen among non-identical twins.
If being trans were purely a social phenomenon, we would not see this step-wise difference where the chance of being trans goes up with increasing genetic similarity.
Our data thus provide strong evidence that genes are involved.
There’s also vectors. Scalars. Tensors.
But the truth is, this is a basic mathematical concept. Not so basic that most people would have access to it, but pretty basic otherwise.
If the user doesn’t have knowledge of a basic concept, getting lost in the weeds is not going to be terribly useful to them. I’m a professor. I answer questions based on the way they’re posed to me.
So, yes, I’m aware. But in this case, I was trying to actually be helpful.
