When I was young, about 7, i remember having to take a dna test for reasons. I also recall my mother pointing out to me that I have more of my father's dna than hers (a significant difference). So for a while I've had this theory in my head that the whole dna thing has something to do with me being trans. Does anyone else have a similar story?

Interesting idea dude. The SRY gene, which is the master gene controlling masculinization, is in the Y chromosome, and thus absent in XX individuals. I would not be too surprise if  there are few XX individuals with a translocated SRY.

I do not remember where the Aromatase or the Alpha feto protein 1 are located, the former is thought to be involved in MTF, and the later on FTM

Granted, I don't know all that much about genes and on top of that I have the problem that English isn't my native language.

But.. as far as I know. You can't have 'more DNA' from either, because it's 50/50. Unless you meant that your father gave you more dominant genes? In that case, I understand what you're saying but I wouldn't know. I've never had it tested.

It's possible that you have more of your dad's dominant genes than recessive and more recessive genes from your mom.

It is possible what those guys said.You can test your genes and find out.

Having more DNA from one parent than another is actually a sign you were conceived through incest @_@. I'm going to assume that's not it :'P. Most likely they just tried to simplify something and ended up wording it very badly xD. Kinda like when I was a kid I was told that Lunchables were made of rat meat ;_;. Later I found out they only mean that they found rats in a factory. It almost ruined my childhood! D:< Damn you bad translations ;_;.

Anyway, I suggest you ask your parents what you were being tested for and what they found :'P. Maybe dig up your medical records.

The SRY gene is present on the X chromosome, but is recessive due to the short arm present on the X. In Y the short arm is deleted allowing the gene to be dominant. At least that was what I was taught but I'm also reaching senility.

Respectfully disagree with you. There is no SRY in normal XX females.

The SRY gene is located on the short (p) arm of the Y chromosome at position 11.3. More precisely, the SRY gene is located from base pair 2,654,895 to base pair 2,655,791 on the Y chromosome.

Mutations on the SRY gene in XY males results in XY females. Translocations of SRY to an X chromosome results in a XX male.

LMao no incest! I guarantee haha. It was a test to see if he was my biological father

My house-mate has a degree in neurobiology, and he and I get into convos about it all the time and yes, you're basically correct.  Every-one gets the same amount of DNA from both genetic parents, but the misconception of "more from one parent" is actually about where one gets the most dominant genes.

As for the "theory" in the original post, I'd wager that parental genetic dominance has nothing to do with it.  While I clearly have more of my father's genetic make-up dominant, my half-sister on my father's side also clearly has paternal genetic dominance, as does my half-sister on our mother's side (my full genetic sister, interestingly, clearly has maternal genetic dominance --assuming, of course, she is my full sister, and knowing my mother, it's possible she's not).  As for the other trans people I know, and among them who they claim to most-resemble (only one of whom I've been able to verify with a photo of her parents), it cuts about fifty-fifty for both trans men and women, as to who has maternal or paternal genetic dominance --which is really how it works for the rest of the world.  Scientifically speaking, it's not a theory because not only is it untested, there's not really any grounds for it to even count as a solid hypothesis.
