in this instance the factor driving the epigenetics and new female or male transcript is endogenous.
Again, no.
If you get alterations inbgene expression due to exogenous (that means from outside) hormones, you do NOT suddenly start making ‘a male transcript.’
There is no such thing as a male transcript (a transcript is the readout of the gene) of any non sex chromosome gene
Not only is that not how epigenetics works, it’s not how genetics works and it’s not how biology works. You do not turn on some sort of hidden female genetic program by adding female hormones.
What you do is alter the adult organism’s appearance to some degree. Breast tissue may grow because both sexes have breast tissue. Musculature may alter somewhat but it can only go so far - you still have a male frame under there. Hair, that kind of thing, may change texture and growth pattern.
These are largely cosmetic changes. They don’t turn one sex into the other because that is coded into each cell when each cell is formed.
I’ve noticed this is a technique being used since a few months back. TRAs take a slew of very impressive sounding words and combine them in a solemn nodding tone to make a point that sounds really serious and sciency. But it’s just a jumble of words that don’t actually mean anything.
And this stuff is fairly niche - I mean I’ve got a twenty year career in it and four degrees so I don’t expect everyone to suddenly be an expert in epigenetics and human genetics but you can see that plenty of posters on here are thinking ... umm no that doesn’t sound right. And they presumably have various levels of science knowledge.
