Being trans definitely has a genetic component or something lol

As the title says me and siblings are all trans all three of us. Me trans women, one year younger trans nonbinary, (potentially trans women they working on it), 2 years younger trans man.

All of us were born 1 year apart. My brother came out first in highschool, then I came out at the end of highschool and then my middle sibling came out in college and recently began questioning their gender further past just nonbinary. IDK if its a genetic thing or a hormone thing mom had or something or if dad had to many pineapples and had fruity cum lol but somethings there. All three of us is crazy
